Barium ferrate purity of the synthesized barium ferrate by performing the reaction at low temperature in the absence of carbon dioxide and by rapidly filtering and drying the precipitate. Addition of a soluble sodium barium salt to an alkali metal ferrate solution produces a maroon precipitate of barium ferrate, a crystal which has the same structure as barium chromate and has approximately the same solubility. The wet method employs chemical and electrochemical techniques. Barium ferrate, BaFeO can be prepared by adding barium oxide to a mixture NaClO and ferric nitrate at room temperature (29± 1 °C). The precipitate formed can then be
Sterling v. Velsicol Chemical Corp. Sterling v. Velsicol Chemical Corp. Sterling v. Velsicol Chemical Corp., 855 F.2d 1188 (6th Cir. 1988), was an environmental lawsuit filed by citizens of Hardeman County, Tennessee, led by Steven Sterling, who sued Velsicol Chemical Corporation for contaminating their water supply through improper disposal of toxic chemicals. In August 1964, Velsicol Chemical Corporation acquired of rural land in Hardeman County, Tennessee. Velsicol used the site as a landfill for by-products from the production of chlorinated hydrocarbon insecticides at its Memphis, Tennessee, chemical manufacturing facility. Before Velsicol purchased the landfill site and commenced depositing chemicals into the ground, it neither conducted
