中文摘要:

      以氢氧化钠做溶剂，用电感耦合等离子体发射光谱法测定土壤中全磷。方法检出限为0.025 mg/kg 。对实际土壤样品进行连续6次测定，方法精密度为1.27﹪～3.40﹪，回收率为95﹪～102﹪。经国家标准物质验证，结果与标准值相符。方法快速、准确。

英文摘要:

      Using sodium hydroxide as the solvent,inductively coupled plasma emission spectrometric determination of total phosphorusr in soil has been carried out. Study shows that the detection limit is 0.025mg/kg. Precision of 6 actual soil samples were 1.27﹪～3.40﹪, and the recovery rate was 95﹪～102﹪. The method has been applied to the determination of phosphorus in national standard reference and the results accord with the certified values. The method is rapid, accurate .
