摘要
采用电感耦合等离子体发射光谱仪测定肥料中有毒有害物质总镍、总钴、总锑重金属元素的含量.此方法准确可靠,校准曲线线性均良好,方法检出限较低,准确度试验中所有元素含量结果均在肥料中镍、钴、硒、钒、锑和铊标准物质给定值范围内,被测元素不受肥料中共存离子干扰,加标回收率为102.3%～103.5%,精密度试验相对标准偏差为 0%～6.20%,符合标准要求.
Abstract
The contents of toxic and harmful substances such as total nickel,total cobalt and total antimony heavy metal elements in fertilizers were determined by inductively coupled plasma emission spectrometer.This method was accurate and reliable,with good linearity of the calibration curve and low detection limit.The results of all elements in the accuracy test were within the given value range of nickel,cobalt,selenium,vanadium,antimony and thallium standard substance in fertilizer,and the measured element was not affected by coexisting ions in the fertilizer.The recovery rate of the added standard was 102.3%-103.5%,and the relative standard deviation of the precision test was 0%-6.20%,which met the standard requirements.
