采用AB-DTPA浸提剂和电感耦合等离子体发射光谱法分析测定了上海土壤样品中8种元素的有效态含量，并与CaCl2-DTPA法比较，结果显示： AB-DTPA法分析土壤Cu、 Zn、 Mg、 Ni、 S、 Cr、 Mo和As 8种元素的有效态含量均高于CaCl2-DTPA法；其中AB-DTPA法测定Cu、 Zn、 Mg、 Ni、 S、 Cr、 Mo 7种元素的有效态含量与CaCl2-DTPA法均达到极显著相关；而ABD-TPA ， CaCl2-DTPA两方法测定土壤有效态的As几乎不相关。结果表明： AB-DTPA法对这8种元素有效态的浸提率高于CaCl2-DTPA法，而两者的分析结果大多相关性好，由此可见， AB-DTPA法更适用于土壤此8元素有效态含量的分析测定。表8，参16。

Soil samples from Shanghai region were selected to determine the available content of eight elements by combining the ammo -nium bicarbonate-DTPA extraction and the inductively coupled plasma atomic emission spectrometry.The analysis results were also compared with the method of CaCl 2-DTPA.The results showed that the available content of Cu ,Zn,Mg,Ni,S,Cr,Mo,As by the method of AB-DTPA was greater than that of the method of CaCl 2-DTPA.The available contents of the seven elements including Cu ,Zn,Mg, Ni,S,Cr,Mo determined by the method of AB-DTPA got an extremely significant correlation with that by CaCl 2-DTPA method.But the available content of as determined by the AB-DTPA method got nearly no significant correlation with that of the CaCl 2-DTPA meth-od.The results showed that the extraction rates of the available content of the eight elements by the AB -DTPA method were higher than the CaCl2-DTPA method,and most of the two methods analysis had a significant correlation.So the AB-DTPA method could get a better result to determine the available contents of the eight elements in soils than the CaCl 2-DTPA method.
