摘　　要：以腾冲硅藻土为基质 ,制得改性硅藻土。测定了该硅藻土对水溶液中 Cu2 +的吸附性能。讨论了焙烧温度、p H值、浓度及时间对吸附性能的影响 ,找到改性硅藻土吸附 Cu2 +的最佳条件。A modified diatomite was prepared using TengChong diatomite by chemical modified. The adsorption properties of this modified diatomite for heavy metal Cu(Ⅱ)was studied in aqueous solution. The effects of the roasting temperature, pH value, concentration of the modified diatomite the solution and adsorption time on the adsorption capacity were discussed. It was found that fine condition of modified diatomite adsorbing Cu(Ⅱ).
