Available in PDF, EPUB and Kindle. Book excerpt: Chemical interaction of RDX on strongly basic ion-exchange resins has been investigated as a method for (1) removal and (2) disposal of RDX from water in a single step. The resin has been evaluated on both laboratory and pilot scales and shows no loss of efficiency after eight regeneration cycles. One cubic foot of resin was found capable of degrading and removing 99% of the RDX contained in 1300 gallons of tap water before regeneration was required. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The United States Environmental Protection Agency (U.S. EPA) Office of Water (OW) initiated the Health Advisory Program in 1978 to provide information and guidance to individuals or agencies concerned with potential risk from drinking water contaminants for which no national regulations currently exist. Since that time, over 100 Health Advisories (HAs) have been published in final form for inorganic, organic, and microbial contaminants. This volume contains HAs for munitions chemicals developed as part of a Memorandum of Understanding between the U.S. EPA and the Department of the Army. To develop each HA, the authors reviewed toxicological data for each chemical and presented the relevant studies to allow an evaluation of the data without continued reference to the primary documents. Each HA has undergone critical internal review by the OW Toxicology Review Panel, EPA program offices, the EPA Reference Dose (RfD) Committee, the EPA Carcinogen Risk Assessment and Verification Enterprise (CRAVE) Committee, and the Army Medical Department (for munitions chemicals only). Finally, the HAs were reviewed by an external panel of experts in toxicology and risk assessments. Drinking Water Health Advisory: Munitions will be an important reference document for all DOD/DOE hazardous waste sites, drinking water professionals, and academic libraries.

Download or read book EPICOR II Resin Degradation Results from First Resin Samples of PF 8 and PF 20 written by and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The 28 March 1979 accident at Three Mile Island Unit 2 released approximately 560,000 gallons of contaminated water to the Auxiliary and Fuel Handling Buildings. The water was decontaminated using a demineralization system called EPICOR-II developed by Epicor, Inc. The Low-Level Waste Data Base Development - EPICOR-II Resin/Liner Investigation Project is studying the chemical and physical conditions of the synthetic ion exchange resins found in several EPICOR-II prefilters. This report summarizes results and analyses of the first sampling of ion exchange resins from EPICOR-II prefilters PE-8 and -20. Results are compared with baseline data from tests performed on unirradiated Epicor, Inc. resins to determine if degradation has occurred due to the high internal radiation dose received by the EPICOR-II resins. Results also are compared with recent findings on resin degradation by Battelle Columbus Laboratories and Brookhaven National Laboratory. Analyses comparing test results of resins from EPICOR-II prefilters PF-8 and -20 with unirradiated resins obtained from Epicor, Inc. show resin degradation has occurred in some of the EPICOR-II resins examined. The mechanism of degradation is compared with work of other researchers and is consistent with their findings. The strong acid cation resins (divinylbenzene, styrene base structure) are losing effective cross-linking along with scission of functional groups and are experiencing first an increase and eventually a decrease in total exchange capacity as the absorbed radiation dose increases. The phenolic cation resins (phenol-formaldehyde base structure) show a loss of effective cross-linking and oxidation of the polymer chain. Analyses of resins removed from EPICOR-II prefilters PF-8 and -20 over the next several years should show a further increase in degradation.

Download or read book Radiation Degradation in EPICOR 2 Ion Exchange Resins written by and published by . This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Low-Level Waste Data base Development -- EPICOR-II Resin/Liner Investigation Program funded by the US Nuclear Regulatory Commission is investigating chemical and physical conditions for organic ion exchange resins contained in several EPICOR-II prefilters. Those prefilters were used during cleanup of contaminated water from the Three Mile Island Nuclear Power Station after the March 1979 accident. The work was performed by EG G Idaho, Inc. at the Idaho Engineering Laboratory. This is the final report of this task and summarizes results and analyses of three samplings of ion exchange resins from prefilters PF-8 and -20. Results are compared with baseline data from tests performed on unirradiated resins supplied by Epicor, Inc. to determine the extent of degradation due to the high internal radiation dose received by the organic resins. Results also are compared with those of other researchers. 18 refs., 23 figs., 7 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Now in its fifth edition, the book has been updated to include more detailed descriptions of new or more commonly used techniques since the last edition as well as remove those that are no longer used, procedures which have been developed recently, ionization constants (pKa values) and also more detail about the trivial names of compounds.In addition to having two general chapters on purification procedures, this book provides details of the physical properties and purification procedures, taken from literature, of a very extensive number of organic, inorganic and biochemical compounds which are commercially available. This is the only complete source that covers the purification of laboratory chemicals that are commercially available in this manner and format.* Complete update of this valuable, well-known reference* Provides purification procedures of commercially available chemicals and biochemicals* Includes an extremely useful compilation of ionisation constants
