建立电感耦合等离子体质谱法（ ICP－MS）测试环境水样中总磷的方法，探讨该方法与传统的光度法在监测结果之间的差异性。结果表明，该方法的检测限可达6×10－4 mg／L，加标回收率在92％～103％之间。氦气碰撞模式可有效解决复杂水样消解后的基体干扰问题，实现对总磷的测定。

The total phosphorus in environmental water samples was determined by ICP-MS.The differences of the determination re-sults obtained using ICP-MS and the traditional spectrophotometric method were compared.The results showed that the detection limit of ICP-MS was 6 ×10 -4 mg/L, and the recovery was in the range of 92%~103%.Additionally, the matrix interference from the digestion of complex water samples was effectively eliminated by using the collision mode of He.
