| Abstract: | 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. |
