　　【化工仪器网政策标准】比色法是通过比较或测量有色物质溶液颜色深度来确定待测组分含量的方法。作为一种定量分析的方法，其原理是基于被测物质溶液的颜色或加入显色剂后生成的有色溶液的颜色，颜色深度和物质含量成正比，则根据光被有色溶液吸收的强度，即可测定溶液中物质的含量，具有操作简单、省时、选择性好、准确性高等优点。

　　近日，一项使用比色法测定聚合物和电子件中六价铬的标准编制完成，正面向社会征求意见。据悉，《电子电气产品中某些物质的测定第7-2部分：六价铬-使用比色法测定聚合物和电子件中的中六价铬(Cr(VI))》是由全国电工电子产品与系统的环境标准化技术委员会归口上报，全国电工电子产品电子产品与系统的环境标准化技术委员会有害物质测量方法分会执行，国家标准化管理委员会主管，中国电子技术标准化研究院主要起草的，其目的是为了适应产业对应对新种类有害物质限制要求和新型检测技术发展，同时又能保持我国RoHS检测技术及结果与一致。

　　阅读标准征求意见稿后可知，为确保《电子电气产品中某些物质的测定第7-2部分：六价铬-使用比色法测定聚合物和电子件中的中六价铬(Cr(VI))》的严谨性和科学性，起草组引用了GB/T 26125-1《电子电气产品中某些物质的测定-第1部分：介绍和概述》以及ISO 3696《分析实验室用水——规范与试验方法》，规定了采用有机溶剂来溶解或膨胀样品基体，随后采用碱消解法从样品中萃取六价铬，研究也表明，有机/碱性溶液与酸性溶液相比能更有效地从可溶解和不可溶解的样品中提取六价铬。

　　标准还指出，对于由ABS(丙烯腈-丁二烯-苯乙烯)、PC(聚碳酸酯)和 PVC(聚氯乙烯)构成的可溶性聚合物，应首先通过适当的有机溶剂将样品溶解，然后通过碱性萃取液来提取样品中六价铬；对于不含锑的不可溶解的或未知的聚合物或者电子件材料，应先将样品放入150℃到160℃的12甲苯/碱性溶液中消解，然后将萃取物中的有机相分离并丢弃，保留无机相来分析六价铬。而在实验过程中，所需要的仪器有真空过滤装置、加热或微波装置、超声波水浴、pH计、分析天平、温度计、比色仪器、研磨机、玻璃量具、消解容器、玻璃分液漏斗、微波消解容器等。

　　随着电子电气产品的飞速发展和广泛使用，其对环境造成的影响也日益引起人们的注意。在这种形势下，世界各国也纷纷通过制定相应的法律法规来保护环境，减少电子电气产品对环境的影响。相信在新标准实施后，能有效测定电子电气产品中的有害物质，继而更好地保护环境。
