磷肥对铅锌矿污染土壤中铅毒的修复作用
|
摘要
在本次研究中,我们采用连续提取的方法能够对象污染的图。利用三种磷肥的化学形态和使用磷肥能够显著降低铅毒性原理进行分析。从三种磷肥对土壤铅污染修复的效果来看,分别为过磁酸钙占百分之八十五左右,钙镁磷肥占百分之八十二,磷矿粉占百分之十五左右。然后将铅形态与其生物有效性结合起米比较,三种磷肥对土壤中铅污染的修复效果比较如下,钙镁磷肥占百分之九十二左右。过磷酸钙占百分之九十左右,磷矿粉占地百分之六十左右。从数据来分析具有恢复铅污染土壤的功能。
In this study, we use continuous extraction method to extract contaminated maps. The chemical forms of three kinds of phosphate fertilizers and the principle that the use of phosphate fertilizers can significantly reduce the toxicity of lead were analyzed. From the effect of three phosphate fertilizers on remediation of lead contamination in soil, it is found that calcium permagnetic acid accounts for about 85%, calcium magnesium phosphate accounts for 82% and phosphate rock powder accounts for about 15%. Then, by comparing lead form with its bioavailability in rice, the remediation effect of three kinds of phosphate fertilizers on lead contamination in soil is as follows: calcium, magnesium and phosphorus fertilizers account for about 92% of the total. Superphosphate accounts for about 90% and phosphate rock powder accounts for about 60%. Data analysis has the function of recovering lead contaminated soil.
