摘要：

采用溶解氧测定方法,基于GB/T 21831-2008《化学品 快速生物降解性：密闭瓶法试验》所规定的试验条件,对GTL烷基苯磺酸的最终生物降解性进行了测试。并对密闭瓶法的若干试验条件做了初步探讨。结果表明：测试样品GTL烷基苯磺酸的最终生物降解度大于60%,符合GB/T 26396-2011《洗涤用品安全技术规范》中对洗涤剂用表面活性剂最终生物降解度的要求。

关键词: GTL烷基苯磺酸, 生物降解, 密闭瓶法

Abstract:

The ready biodegradability of GTL-alkylbenzene sulfonic acid was studied by closed bottle test based on the national standard GB/T 21831-2008 “Chemicals-ready biodegradability: closed bottle test”. Some test conditions in the closed bottle test were also optimized. The results showed that the ready biodegradability of GTL-alkylbenzene sulfonic acid was over 60%, which met the requirements of national standard GB/T 26396-2011 “Technical specification for safety of soaps and detergents” for the surfactants used in soap and detergent formulation.

Key words: GTL-alkylbenzene sulfonic acid, biodegradability, closed bottle test
