Abstract
Calcium, cobalt, manganese, calcium-cobalt, calcium-manganese, and cobalt-manganese phosphates were prepared in aqueous solution. Their chemical composition and thermal behavior of obtained phosphates were investigated by ICP, TG-DTA, XRD, and FT-IR. Specific surface area of thermal products was calculated by BET method. The removal of lead was tested with these thermal products. The relationship between the chemical composition and lead removal effects was studied.
