| Abstract: | A method for the determination of impurity elements Na,K,Mg and Ca in high purity silicasol by FAAS has been developed.Under the optimum condition,the detection limits of Na,K,Mg and Ca are 0.0047,0.0060,0.0036,0.028μg/mL.The recovery were between 92.5%-112.5%,RSD were all less than 10%.The methods is accurate,rapid and convenient. |
