Available in PDF, EPUB and Kindle. Book excerpt: Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.

Download or read book Comparative Adsorption Study Of Methylene Blue On Low Cost Adsorbent written by Sanu Paul and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low cost adsorbent are prepared from activated sugarcane bagasse (ASB), activated waste paper (AWP), and activated Delonix regia Fruit Pod (ADRF)which act as a useful adsorbent for the removal of methylene blue from aqueous phase. The study was carried out using batch experiments with synthetic wastewater having a methylene blue concentration. The effects of contact time were investigated and compared for all the three adsorbents. The adsorption process reached equilibrium within 120min of contact time almost for all adsorbent. Comparative study of contact time indicates that sugarcane bagasse adsorbed at faster rate and adsorbed the maximum. The Freundlich, Langmuir, models were used for mathematical description of the adsorption equilibrium, and it was found that the experimental data fitted very well to the Langmuir isotherm for all the three adsorbent. Batch adsorption studies, based on the assumption of a pseudo-first-order, pseudo-second-order, showed that the kinetic data followed closely a pseudo-second-order rather than a pseudo-first-order mechanism.

Download or read book Application of Adsorbents for Water Pollution Control written by Amit Bhatnagar and published by Bentham Science Publishers. This book was released on 2012-11-11 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural and industrial waste materials. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control. This handy reference work is intended for researchers and scientists actively engaged in the study of adsorption and the development and application of efficient adsorption technology for water treatment. This e-book covers a wide range of topics including modeling aspects of adsorption process and the applications of conventional and non-conventional adsorbents in water remediation emphasizing sorption mechanisms of different pollutants on the adsorbents.

Download or read book Adsorption of Methylene Blue by Using Activated Carbon from Empty Fruit Bunch and Palm Press Fiber written by Siti Aisyah Radhiah Mohamed @ Ayub and published by . This book was released on 2012 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Empty Fruit Bunch (EFB) and Palm Press Fiber (PPF) are abundance of agricultural wastes. These fiber are basically incinerated and used in mulching purposes. Adsorption of methylene blue by using both of fiber is one way to increase the uses of them. Methylene blue is one of dyestuff that harmful to human and aquatic life. Effect of contact time, agitation speed and dosage of activated carbon is investigated. Activation the activated carbon using impregnated of KOH solution is used. Same ratio of fiber which is (1:1) (wt %) is prepared. The higher the contact time, the higher the amount of adsorption capacity obtained. At certain time there got the lower number of adsorption capacity because the contact time taken is not sufficient since the process of adsorption taking a long time to achieve the equilibrium. In term of agitation speed, 170 rpm of speed gave the highest adsorption capacity compared to 200 rpm and 700 rpm. According to Langmuir isotherm model, it is showed that 170 rpm gave 5.025 mg/g of adsorption capacity. It is because the Van der Waals forces are weak to bind the molecules. So, the molecules that already attracted to the molecules surface are desorbed back if the agitation speed too high. For dosage impact, the adsorption capacity decreased sharply with the increasing of adsorbent dosage because of the overlapping of adsorption site that cause the overcrowding of adsorbent particles.

Download or read book A Natural Adsorbent Sea Shell for Removal of Methylene Blue written by Dr. Papita Saha and published by LAP Lambert Academic Publishing. This book was released on 2010-12 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methylene blue, a thiazine (cationic) dye, has been commonly used for dyeing of silk, leather, plastics, paper, cotton mordanted with tannin, and also in manufacturing of paints and printing inks. Although methylene blue is not hazardous compared to other commercial dyes, acute exposure to methylene blue can cause increased heart rate, vomiting, diarrhea, nausea and shock. Potential exposure to methylene blue can also cause hypertension, pre-cordial pain, dizziness, headache, fever, fecal discoloration, profuse sweating, mental confusion, ethemoglobinemia and hemolytic anemia. Hence, there is a necessity for the treatment of effluent containing such dye due to its harmful impacts on receiving waters. Amongst the numerous techniques of dye removal, adsorption is the procedure of choice owing to its low initial cost, high efficiency and ease of operation. A large number of adsorbents especially agricultural wastes have been investigated for their efficacy as adsorbents. A Natural Adsorbent - Sea Shell for Removal of Methylene Blue" describes the potential use of sea shell for the removal of methylene blue from aqueous systems.
