目前需要有机磷酸酯(OPE)抗氧化剂,因为它们有助于提高聚合物的质量,包括聚丙烯(PP)。在这项研究中,提出了一种从工业废水中有效提取双(2,4-二异丙苯基)季戊四醇二亚磷酸酯的整体方法。在采用固相萃取(SPE)技术时,使用高效液相色谱(HPLC)对回收的化合物进行全面分析,质谱(MS),热分析(TGA),傅里叶变换红外光谱(FTIR),和差示扫描量热法(DSC)。随后,纯化的双(2,4-二异丙苯基)季戊四醇二亚磷酸酯在掺入PP树脂后被评价为热氧化稳定剂。相对标准偏差(RSD),错误(Er),线性度(R2),和百分比(%)回收率分别小于2.6、2.5,显著大于0.9995,大于96%,分别,用于色谱方法和SPE的日间和日间测试。除了氯仿,由于所研究分析物的溶解度特性,这是必要的,使用环保溶剂,如甲醇和乙腈,是在这项研究的发展过程中考虑的。用FTIR对从工业废水中提取的OPE进行了表征,UV-Vis,DSC,TGA,MS,允许阐明双(2,4-二异丙苯基)季戊四醇二亚磷酸酯(BDPD)的结构。将回收的OPE与PP树脂混合,使其能够改善其热性能并最大程度地减少其热氧化降解。废水中有机磷阻燃剂(OPE)的浓度令人担忧,范围从1179.0到4709.6mgL-1。这些超过了水生生物的毒性阈值,强调全球环境风险。使用经过验证的固相萃取(SPE)技术,回收率超过94%,该研究通过去除有机污染物和支持循环经济原则来解决人们的担忧。恢复BDPD的高度经济和环境意义强调了紧急全球关注和干预的必要性。
Organic phosphoester (OPE) antioxidants are currently required due to their contribution to enhancing the quality of polymers, including polypropylene (PP). In this research, an integral methodology is presented for the efficient extraction of bis(2,4-dicumylphenyl) pentaerythritol diphosphite from industrial wastewater. Upon employing the solid-phase extraction (SPE) technique, the recovered compound is subjected to a comprehensive analysis of the recovered compound using high-performance liquid chromatography (HPLC), mass spectrometry (MS), thermal analysis (TGA), Fourier transforms infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC). Subsequently, purified Bis(2,4-dicumylphenyl) pentaerythritol diphosphite was evaluated as a thermo-oxidative stabilizer after incorporation into PP resins. The relative standard deviation (RSD), Error (Er), linearity (R2), and percentage (%) recovery were less than 2.6, 2.5, more significant than 0.9995, and greater than 96%, respectively, for the inter-day and intra-day tests of the chromatographic method and the SPE. Except for chloroform, which was necessary due to the solubility properties of the investigated analyte, the use of environmentally friendly solvents, such as methanol and acetonitrile, was considered during the development of this research. The OPE extracted from industrial wastewater was characterized by FTIR, UV-Vis, DSC, TGA, and MS, allowing the elucidation of the structure of Bis(2,4-dicumylphenyl) pentaerythritol diphosphite (BDPD). The recovered OPE was mixed with PP resins, allowing it to improve its thermal properties and minimize its thermo-oxidative degradation. Organophosphorus flame retardant (OPE)\' concentration in wastewater is alarming, ranging from 1179.0 to 4709.6 mg L-1. These exceed toxicity thresholds for aquatic organisms, emphasizing global environmental risks. Using a validated solid-phase extraction (SPE) technique with over 94% recovery, the study addresses concerns by removing
organic contaminants and supporting circular economy principles. The high economic and environmental significance of recovering BDPD underscores the need for urgent global attention and intervention.
