摘要 采用离子色谱法测定不同老化程度农用塑料薄膜中的硫酸根离子含量,间接测得硫含量,证实了农用塑料薄膜中的含硫量相对其老化程度存在一定的相关性。通过实验选择合适的样品预处理方法和色谱条件,建立了农用塑料薄膜中SO42-的定量分析方法。SO42-浓度在0.1~100mg/L的范围内呈线性,其标准曲线的线性回归系数为0.9999,检测限为0.05mg/L,重现性好。 The sulfur content in agricultural polyethylene (PE) film was indirectly determined by ion chromatography through the determination of sulfate content in agricultural polythylene film with different aging levels. The results demonstrated that there was a relativity between sulfur content and aging levels. Sample preparation method and chromatographic conditions were selected through experiments. A linear relationship was in the range of 0. 1-100mg/L for SO4^2- , the regression coefficient was 0. 9999, and the detection limit was 0. 05mg/L, with good reproducibility.
