A method for determination of Be ,K ,Li in zirconium alloy by ICP‐OES was established. The way of sample pretreatment was determined. Spectral lines of each element were selected. The matrix matching method was used to eliminate interference brought by the base of zirconium in these elements. The precision and accuracy of the method were tested. The results showed that the relative standard devia‐tions (RSD) for each element were all less than 5% ,and the recoveries were 95% 106%. The experi‐ments show that the method is rapid ,accurate and applicable to simultaneous determination of Be ,K ,Li in zirconium alloy.
