磷石膏及磷石膏土壤调理剂中多种水溶性有害元素的离子色谱分析方法

Ion Chromatographic Method for the Analysis of Multiple Water-Soluble Harmful Elements in Phosphogypsum and Phosphogypsum Soil Conditioner

摘要: 本研究聚焦磷石膏及磷石膏土壤调理剂领域，详细阐述了采用离子色谱法分析云南磷石膏及磷石膏土壤调理剂中多种水溶性有害元素的方法。在实际应用场景下，磷石膏的不合理利用会污染土壤和水体，进而造成生态环境的污染。本实验采用离子色谱法，通过建立标准曲线、优化样品前处理及仪器分析条件，实现了对F⁻、Cl⁻、$N{O}_2^{-}$ 、$N{O}_3^{-}$ 、$S{O}_4^{-}$ 和$P{O}_4^{-}$ 等有害元素的精准检测。该方法具有良好的线性关系、较低的检出限和较高的精密度，为磷石膏土壤调理剂的质量控制和环境安全性评估提供了有力的技术支持，促进磷石膏资源化有效利用和磷肥行业可持续发展。

Abstract: This study focuses on the field of phosphogypsum soil conditioner, and details the method of analyzing various water-soluble harmful elements in phosphogyum and phosphogypsum soil conditioner by ion chromatography. In practical application scenarios, the unreasonable use of phosphogypsum can lead to soil and water pollution, and cause environmental pollution. In this experiment, ion chromatography was used to achieve accurate detection of harmful elements such as F⁻, Cl⁻, $N{O}_2^{-}$ , $N{O}_3^{-}$ , $S{O}_4^{-}$ , and $P{O}_4^{-}$ by establishing a standard curve, optimizing sample pretreatment and instrument analysis conditions. The method has a good linear relationship, low limit of detection and precision, and provides strong technical support for the quality control and environmental safety assessment of phosphogypsum soil conditioner, and promotes the effective utilization of phosphogypsum resources and sustainable development of the phosphate fertilizer industry.
