中药渣有机肥中重金属元素Pb、Cd、Cr的评价
|
摘要
目的:了解中药渣有机肥中重金属元素Pb、Cd、Cr的含量。方法:用电感耦合等离子体发射光谱仪检测,并与污泥有机肥进行比较。结果:用中药渣制备的有机肥中Pb、Cd、Cr单项污染指数很低,且综合污染指数也仅为0. 061,但用污泥制备的有机肥中Cr的单项污染指数为1. 27,偏高,而综合污染指数也大于1. 00,为轻度污染。结论:中药渣有机肥中Pb、Cd、Cr含量符合NY 525-2012标准要求,但污泥有机肥中Pb、Cd、Cr含量较高,Cr超标1. 27倍,存在安全隐患。
Objective Inductively coupled plasma emission spectrometer was used to detect the Pb,Cd,Cr in organic fertilizer prepared from Chinese medicine residue. Method The organic fertilizer prepared from the sludge was used as comparative sample. Result Results showed that the organic fertilizer prepared from Chinese medicine residue contented a little amount of Pb,Cd,Cr. Its comprehensive pollution index was 0. 061,much lower that of sample prepared from the sludge,which arrived at 1. 00. Conclusion The content of the Pb,Cd,Cr in organic fertilizer prepared from Chinese medicine residue meets the NY 525-2012 stand,contrary to them in the sample prepared from the sludge.
