摘要
Abstract
A simple,fast,accurate and sensitive method was established to determine the metal element in water-soluble fertilizers by ICP-AES. Six elements such as Fe,Mg,Ca,Mn,Cu and Zn were simultaneously determined.The results showed that the detection limit of arsenic was decreased from 0.003μg/mL to 0.008μg/mL.The linear ranges were beyond three orders of magnitude.The method was applied to the determination of water-soluble fertilizers.The recoveries of spiked standard were 91.7%~106.2%.RSD of the peak area for the seven successive injections of irrigation water was less than 5%.关键词
