摘　　要：通过原子吸收光普法研究了南瓜对铅的吸收特性,结果表明:南瓜对铅的吸收量随时间的延长而增加,吸收速率随时间的延长而降低;培养液pH7时对铅的吸收量最大;这一结论与南瓜对重金属镉的吸收特性相似。A study was carried out on the characteristic of lead absorption in pumpkin via atomic absorption spectrophotometer. The results showed that lead absorption amount in pumpkin increased with time, but the absorption rate decreased with time; And the lead absorption amount reached the peak in pH 7. Lead and cadmium have similar characteristic of absorption in pumpkin.
