The ability of calcium peroxide (CaO2) to immobilize As of contaminated soil was studied using pot and field experiments. In pot experiment, CaO2 applied at 2.5 and 5 g kg 1 significantly increased celery shoot weight and decreased shoot As accumulation, which was ascribed to the formation of stable crystalline Fe and Al oxides bound As and the reduction of labile As fractions in the soil. The labile As fractions were pH dependent and it followed a ‘‘V’’ shaped profile with the change of pH. In… CONTINUE READING
