Abstract

This study introduces a novel Direct Organic Introduction (DOI)—Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) method for quantifying platinum (Pt) in polysiloxanes. The method simplifies sample pretreatment, enhancing the repeatability and accuracy of analysis. Optimized parameters led to a rapid, accurate method with a low detection limit of 0.460 mg/kg and high linearity (r > 0.9999). The method’s relative standard deviation (RSD) was 0.6%-1.4%, and recovery rates were 95.2%-106%, outperforming traditional digestion methods in terms of simplicity and accuracy. Through AGREEprep evaluation, which is an analytical greenness metric for sample preparation, the DOI method demonstrated superior greenness compared to acid digestion methods. The establishment of this method is of great importance for the synthesis and de-plating effect evaluation of polysiloxanes, as well as the precise quantification of Pt in platinum catalysts. It provides an efficient and environmentally friendly analytical technique for research and applications in related fields.

直接有机引入-电感耦合等离子体发射光谱法测定聚硅氧烷中的铂

本研究介绍了一种新的直接有机引入(DOI) -电感耦合等离子体光学发射光谱（ICP-OES）方法，用于定量聚硅氧烷中的铂（Pt）。该方法简化了样品前处理，提高了分析的重复性和准确性。优化后的方法快速、准确，检出限0.460 mg/kg，线性度高（r > 0.9999）。方法相对标准偏差（RSD）为0.6% ~ 1.4%，回收率为95.2% ~ 106%，简便、准确，优于传统消化法。通过对样品制备的分析绿度指标AGREEprep评价，DOI方法的绿度优于酸消化方法。该方法的建立对于聚硅氧烷的合成和脱镀效果评价，以及铂催化剂中铂的精确定量具有重要意义。为相关领域的研究和应用提供了一种高效、环保的分析技术。
