摘　　要：重金属含磷物质原位化学修复是通过添加不同的含磷物质钝化土壤中重金属元素,改变重金属在土壤中赋存状态,降低其生物有效性的一种有效方法。由于操作方便、效果迅速和价格低廉,含磷物质进行重金属污染土壤原位修复被认为是目前有效的修复措施。对目前国内外利用含磷物质钝化重金属污染土壤研究现状进行了综述,就含磷物质种类、修复化学作用机制、影响因子以及其在重金属修复方面的局限性等方面进行了探讨,并提出研究方向。Chemical immobilization using phosphorous-containing materials cause heavy metals in soils to shift from forms with high availability to the most strongly bound fractions.Phosphate-containing materials utilization was proposed as the best management practice for remediation of heavy metals polluted soils for its easy operation,efficiency and low-cost.Current studies involving in-situ remediation of heavy metals polluted soils using phosphorous-containing materials were reviewed.The types of phosphorous-containing materials,the mechanism,influential factors and limitation of the remediation using phosphorous-containing materials were discussed in detail.Meanwhile,the research tendency and development prospects of the remediation technologies using phosphorous-containing materials were forecasted in dealing with heavy metals polluted soils.
