摘　　要：利用ORS—ICP-MS测定纯铜中的磷。对ICP-MS测定条件进行了最佳化的选择，利用动态反应池技术（ORS）和在线内标加入技术，可降低基体干扰，提高灵敏度。分析方法的检出限为0．33ng／mL，加标回收率为94％～97％。ICP-MS with octopole reaction system （ORS） has been used for determination of phosphorus in pure copper. The optimum conditions of ICP-MS for the method were investigated. By the ORS technology and on-line internal standard addition method, the matrix interference was decreased and the sensitivity was increased. The detection limits is 0.33 ng/mL. The recoveries of the method are in range of 94% - 97%.
