The principal sources of chlorine in the MSW feed to WTE power plants are food wastes (e.g., wheat, green vegetables, melon, pineapple), yard wastes( leaves, grass, etc.), salt (NaCl), and chlorinated plastics (mostly polyvinyl chloride). Chlorine has important impacts on the WTE operation in terms of higher corrosion rate than in coal-fired power plants, formation of hydrochloric gas that must...

In the structure of the title complex, [Cs(C6H2Cl3N2O2)(H2O)] n , the caesium salt of the commercial herbicide picloram, the Cs(+) cation lies on a crystallographic mirror plane, which also contains the coordinating water mol-ecule and all non-H atoms of the 4-amino-3,5,6-trichloro-picolinate anion except the carboxyl-ate O-atom donors. The irregular CsCl4O5 coordination polyhedron comprises ch...

Electrolyzed strong acid water (ESW) containing free chlorine at various concentrations is becoming to be available in clinical settings as a disinfectant. ESW is prepared by electrolysis of a NaCl solution, and has a corrosive activity against medical instruments. Although lower concentrations of NaCl and free chlorine are desired to eliminate corrosion, the germicidal effect of ESW with low N...

The influence of chlorine levels, the concentration of dissolved organic carbon and the abundance of bacteria in suspension, on the formation of biofilms on experimental glass surfaces were evaluated. Twelve reactors, packed with glass spheres, were continuously perfused with tap water. The properties of water were altered in different ways: chlorine was neutralized by the addition of thiosulfa...

tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...

The paper describes the chemical modification of PVC consisting in introduction amino groups (1,4-dioxane, diethylenetriamine), and then cross-linking with dichlorodiethyl ether. optimal extraction time was obtained for polymer that had more chlorine atoms substituted diethylenetriamine polymers were characterized by infrared spectroscopy (FTIR), elemental analysis (CHN) differential thermal (D...

This study examined the effect of chlorine treatment on the infectivity of hepatitis A virus (HAV). Prodromal chimpanzee feces, shown to induce hepatitis in marmosets (Saguinus sp.), was clarified, and the virus was precipitated with 7% polyethylene glycol 6000, harvested, and resuspended. The suspension was layered onto 5 to 30% linear sucrose gradients and centrifuged; the fractions containin...
