摘要
本方法采用三次拟合计算法处理土壤样品中硫含量的测试结果。试样采用传统的燃烧碘量法进行处理,在结果计算中使用三次拟合法处理测试结果,取得令人满意的效果。本方法的精密度为1.54%5.38%,方法检出限(3S):0.005%,较好的满足土壤样品中硫的测试要求。
It uses cubic fitting equation to treat the sulfur determination in the soil simple.The specimens are treated by traditional Combustion iodometry,the testing result in calculation is treated by cubic fitting equation and the effect is fine.The precision of this method is 1.54% to 5.38%,the method detection limit（3S） is 0.005%,satisfies the requirement of the sulfur determination in soil simple.
