摘要:
采用五步连续提取法研究了2种生物炭对复合污染土壤中Cu、Pb、Zn和Cd的化学提取态的影响。结果表明,施加2种生物炭后,土壤中4种重金属生物有效态的含量均下降。对照处理中4种重金属主要以残渣态的形式存在,其中Zn、Pb、Cd和Cu所占的比例分别为79.0%、77.5%、75.0%和63.0%。施加猪粪生物炭后,Zn、Pb和Cd水溶态与交换态占总含量的比例下降,Pb、Cu和Cd的残渣态所占比例增加。施加稻壳生物炭后,Pb和Cd的残渣态所占比例增加,碳酸盐结合态、铁锰氧化物结合态、水溶态与交换态比例均下降;Zn和Cu的碳酸盐结合态比例下降,残渣态比例增加。添加猪粪生物炭和稻壳生物炭后Pb、Cu的残渣态比例分别增加了8.4%、5.8%和7.9%、9.5%;表明添加2种生物炭可以降低Pb、Cu的有效性,但比例相差不大。
