Abstract:
The ICP -AES method for the determination of phosphorus in water is described.The optimum conditions fo r the determination are tested and discussed.Under the optinum co nditions, the detection limits of is P0.02 mg/L respectively.The recoveries of the method are 96.5 % ～ 102.1 %, RSD 1.65 %～ 2.83 %.Thismethod is accurate, quick-acqui red and convenient.It is used in the determinat ion of water w ith satisfacto ry results.
