1/7/2000· The chemical amendments, calcium carbonate, steel sludge, and furnace slag, may reduce the concentration of Cd in brown rice, Chinese cabbage and wheat grain. The most effective is furnace slag from a coined evaluation of the effect on plant yields and Cd concentration in plants.

Titanium - Essential Chemical Industry

Titanium. Titanium and its alloys have a very favourable strength to mass ratio. They are also resistant to corrosion because their surface develops a thin, but very resilient, oxide layer. Thus they are used where strength, lightness and resistance to corrosion are important. Although the use of titanium is limited by its high cost, new

Determining Total Hardness in Water Chemistry Tutorial

The Calculations The balanced chemical equation for the reaction between calcium and magnesium ions and EDTA is: Ca 2+ + H 2 EDTA 2-→ CaEDTA 2-+ 2H + Mg 2+ + H 2 EDTA 2-→ MgEDTA 2-+ 2H + So if we let M 2+ be the total of Ca 2+ and Mg 2+ ions in solution then:
