摘要:
羟丙基-β-环糊精(HPCD)和β-环糊精(BCD)具有增溶土壤铅离子的潜力。试验中土壤铅污染浓度设置为600、1 200 mg/kg,螯合剂浓度为土壤铅浓度的0.5、1.0倍,通过与EDTA增溶效果作比较,分析HPCD和BCD对土壤铅离子的增溶作用。结果表明,加入3种螯合剂,土壤有效态铅离子浓度均与对照组存在显著差异,增溶作用符合HPCD>EDTA>BCD>CK,且HPCD与EDTA间无显著差异,而BCD与EDTA存在显著差异,表明HPCD对土壤铅离子的增溶作用与EDTA接近,高于BCD;当土壤污染浓度一定时,随着螯合剂浓度提高,土壤有效态铅离子浓度增加;同时螯合剂浓度一定时,随着土壤铅污染浓度的提高,可溶态铅离子浓度增加,说明螯合剂浓度和土壤铅污染浓度是影响螯合剂增溶效果的因素;HPCD和BCD均对土壤铅具有显著的增溶作用,且HPCD具有替代EDTA的可能性。
