摘要:
建立了艾士卡-离子色谱测定植物中含硫量的方法,该法利用植物样品与艾士卡试剂的混合灼烧,将植物中的硫转化为硫酸盐进行测定,再根据硫酸根的含量计算植物中含硫量。经验证,该方法检出限为0.01%,精密度为2.3%~3.9%,回收率为91.7%~104.3%,适用于植物中含硫量的测定。

Abstract:
An Eschka ion chromatography method for the detection of sulfur content in plants was establish. The sulfur in plants was converted to sulfate radical by burning a mixture of plant samples and Eschka mixture and then the sulfur content in plants was calculated according to the content of sulfate radical. The results showed that the detection limit was 0.01%, the precision was 2.3%~3.9%, the recovery rate was 91.7% ~ 104.3%. The method were suitable for the detection of sulfur content in plants.
