【摘要】 通过综合分析比较九种活性提取剂对２１个污染土壤镉的提取能力，土壤基本性状对提取量的影响，以及提取量与土壤中镉赋存形态的关系，提出了以０．０５ｍｏｌ／ＬＣａＣｌ＿２作为评价污染土壤活性镉的最佳提取剂。更多还原

【Abstract】 Abstract Abstract Nine available cadmium extractants,including 0.01 mo1/L HCl,0.05mol/LHCl,0.1mol/LHCl,0.01m ol/LCaCl₂,0.05m ol/LCaCl₂,0.1m ol/LCaC1₂,2.5%HOAc,1mol/LNH₄OACand1mol/LNH₄NO₃were studied toextract cadmium in soils contaminated by a copper smelter. By com paring thepercentage of cadmium extracted by these extractants, the relationship ofcadmium solubilized with some soil properties and soil cadmium formation s,0.05mol/LCaCl₂ was the best extractant to assess the cadmium availabilityin contaminated soils.更多还原
