Recently,the test means adopted widely are AA and ICP, but photometry and polarography still occupy a certain position in soil test of trace elements,because of their handy equipments and the improvement of their sensitivity and accuracy.

- 現代測試手段發(fā)展到廣泛采用原子吸收光譜(AA)和電感耦合等離子體發(fā)射光譜(ICP),但比色法(光度法)和極譜法不僅設備比較簡(jiǎn)便,而且新的顯色劑、催化系統等方面的研究進(jìn)展,使其對某些元素的測定靈敏度和準確度超過(guò)AA和ICP,從而在微量元素測試技術(shù)中仍占據一定地位。
