One of the barriers to the recycling of chrome plated acrylonitrile–butadiene–styrene (ABS) is the degradation caused by the solution containing nitric acid used in the pickling of the metal layer. In this study, defective chrome plated ABS parts were pickled in a solution composed of lactic and sulfuric acids and hydrogen peroxide, and recycled by injection molding with different proportions of virgin ABS. The influence of pickled ABS on the chemical composition, thermal and mechanical properties of the samples was evaluated. The samples were chrome plated and characterized by visual inspection and adhesion tests. A slight yellowing of the virgin ABS/pickled ABS samples was observed due to the degradation of butadiene component. The thermal and mechanical properties were similar to those of virgin ABS. After the new chrome plating, all samples were approved in the adhesion tests, demonstrating that pickled ABS can be recycled by injection molding and chrome plating.

镀铬丙烯腈-丁二烯-苯乙烯（ABS）回收利用的障碍之一是金属溶液酸洗中所用的硝酸溶液引起的降解。在这项研究中，将有缺陷的镀铬ABS零件在由乳酸，硫酸和过氧化氢组成的溶液中进行酸洗，然后通过注模与不同比例的原始ABS一起进行回收。评估了腌制的ABS对样品的化学成分，热和机械性能的影响。样品镀铬并通过目测和附着力测试进行表征。由于丁二烯组分的降解，观察到原始的ABS /腌制的ABS样品略微泛黄。热和机械性能与原始ABS相似。新镀铬后，
