1) Available calcium
有效态钙
5) available Cd
有效态镉
1.
The available Cd in the soil was extracted by using four kinds of extracting solvent at different temperature,time and ratio of soil to solvent.
用４种提取剂在不同温度、时间和土液比条件下，对褐土有效态镉含量分别进行提取试验。
2.
It is essential to establish a suitable extraction method for available Cd for acid soils because the available, instead of total amounts of Cd are more and more frequently used as criteria for assessing soil environmental quality.
结果表明,不同提取剂对有效态镉的提取率明显不同,但都存在土壤全镉含量高提取率低,土壤全镉含量低提取率高的趋势;0。
6) available Pb
有效态铅
1.
According to the method for determination of available forms of heavy metals in soil extracted with DTPA,the amounts of available Pb and Cd in a soil was determined with atomic absorption spectrometer.
以DTPA为提取剂,用原子吸收分光光度计测定土壤中的有效态铅和镉,多次实验室间和实验室内的对比试验表明,其方法可靠,精密度和允许偏差都在国家标准允许范围内。
