For Zn, Mn, Pb and Cd, satisfying results was,achieved by adding ash from stove and phosphorite powder （FA20, PR10）, phosphorite powder and lime （PR15, CL10）, ash from stove and phosphorite powder （FA10, PR10）, and ash from stove and peat （FA20, PT 10）. Based on their effects of inactivating available forms of heavy metals, ash from stove, phosphorite powder and peat were supposed to be effective inactivators with optimum percentages of 20%, 15% and 10% （FA20, PR15, PT10）.展开更多
