UV filters and parabens, as ingredients of cosmetics, are commonly occurring water pollutants. In our work, nutshells were used as biosorbents in the developed analytical procedure for the determination of UV filters and parabens in water samples. The shells obtained from walnuts, hazelnuts, peanuts and pistachios were applied as biosorbents. The proposed analytical method can be used as a powerful alternative to other methods for the analysis of UV filters and parabens in water samples. A method of carrying out the sorption step and its parameters, i.e., the effect of time, pH, and salt addition, was developed. A method for the desorption of analytes was also developed, in which the type and volume of solvent, and the desorption time, were established. The recoveries were in the range of 59-117% for benzophenones and lower recoveries from 14 to 75% for parabens. The results showed that nutshells can be used as low-cost, efficient and eco-friendly biosorbents for the determination of parabens and UV filters in water samples. These materials can be used as a 'greener' replacement for the commercially available adsorbents for the extraction of cosmetic ingredients from the environment.
紫外线过滤剂和对羟基苯甲酸酯作为化妆品成分，是常见的水污染物。在我们的工作中，坚果壳被用作生物吸附剂，用于开发测定水样中紫外线过滤剂和对羟基苯甲酸酯的分析方法。从核桃、榛子、花生和开心果中获得的壳被用作生物吸附剂。所提出的分析方法可作为水样中紫外线过滤剂和对羟基苯甲酸酯分析的其他方法的有力替代方法。开发了一种进行吸附步骤及其参数的方法，即时间、pH值和加盐的影响。还开发了一种分析物解吸方法，确定了溶剂的类型和体积以及解吸时间。二苯甲酮的回收率在59-117%范围内，对羟基苯甲酸酯的回收率较低，在14-75%之间。结果表明，坚果壳可作为低成本、高效且环保的生物吸附剂，用于测定水样中的对羟基苯甲酸酯和紫外线过滤剂。这些材料可作为从环境中提取化妆品成分的市售吸附剂的“更绿色”替代品。
