摘　　要：为了研究餐(饮)具中阴离子合成洗涤剂残留量的影响因素,本文首先模拟了常用的2种不同的洗涤方式进行了试验;为了找出残留的主要影响因素,本文又对餐(饮)具材质、洗涤水温和洗涤剂品牌这3个影响因素进行了三因素三水平的正交试验。试验结果表明:流水洗涤的方式洗涤剂残留量要低于浸泡洗涤的方式;洗涤剂残留量影响因素大小排序为:餐具材质>洗涤剂品牌>清洗水温;残留量按餐具材质排序如下:密胺材质残留量>陶瓷材质残留量>不锈钢材质残留量;静态洗涤的情况下,由于清洗不充分和交叉污染,会造成洗涤剂的残留;密胺材质餐具属高分子聚合物,其表面的密胺光亮膜对大分子物质有吸附作用,导致残留较多;某些品牌洗涤剂的成分中阴离子表面活性剂浓度较高可能导致残留较高。日常生活中为了减少洗涤剂残留,应采用流水洗涤的方式,选用不锈钢或者陶瓷材质的餐具,同时选择市场口碑较好的洗涤剂品牌按照说明适量添加。To investigate the key factors affecting the residues of anionic synthetic detergents on tableware,this paper first simulated two different washing methods.To identify the primary factors influencing detergent residues,an orthogonal test with three factors at three levels was conducted,focusing on tableware material,washing water temperature and detergent brand.The experimental outcomes revealed that the detergent residual levels were lower with the running water washing method compared to the soak washing method.The influencing factors for detergent residue were prioritized as:tableware material>detergent brand>cleaning water temperature.Residue according to tableware material as follows:melamine material residue>ceramic material residue>stainless steel material residue.Static washing can lead to detergent residues due to inadequate water cleaning and cross-contamination.Melamine tableware,a type of high molecular weight polymer,has a surface film that adsorbs macromolecular substances,thus retaining more residues.Higher concentrations of anionic synthetic detergents in some brands of detergent ingredients may result in higher residues,which contributes to increased residues.In order to reduce detergent residue in daily life,we should adopt the way of running water washing,choose stainless steel or ceramic tableware,at the same time choose the market reputation better detergent brand to add the right amount according to the instructions.
