土壤全磷全钾同时测定方法研究
Study on Simultaneous Determination of Total Phosphorus and Total Potassium in Soil
摘要
Abstract
[Objective]To study a method for simultaneous determination of total phosphorus and total potassium in soil.[Method]According to the range of the standard curve of the instrument, choosing the appropriate dilution multiple, the phosphorus and potassium content in the digestion solution were determined to complete the determination of total phosphorus and potassium in soil samples.[Result]The linear coeffi-cients of phosphorus and potassium were 0.999 9 and 1.000 0,respectively.The standard soil samples could be accurately within the standard value range,and there was no significant difference between the study and natinal standard method.[Conclusion]The study provides a rapid and efficient method for the detection and analysis of total phosphorus and total potassium in soil,and it is of practical significance to detect the content of and total phosphorus total potassium in soil and quickly guide the production.关键词
