摘要
以甲烷作为瓦斯的模型气体,设计出一种由阴离子表面活性剂和非离子表面活性剂复配而成的复合胶束液瓦斯吸收剂。将阴离子表面活性剂SDS分别与非离子表面活性剂TX-100、TW80、OP-7、EL-20、BS-12按不同比例配置成一定浓度的复合胶束水溶液,利用气相色谱仪测定其对甲烷的吸收效果,并进行定量比较,结果发现SDS与BS-12按1:2.5配置成的复合胶束液在所有试样中吸收效果最好。通过激光粒度分析仪分析复合胶束液的胶束粒径及聚集状况,对不同胶束液对甲烷吸收效果的差异进行分析,结果表明,复合胶束液对甲烷的吸收效果与胶束核内微区的空间大小有关,吸收效果较好的胶束液具有较大的胶束粒径。
A kind of gas absorbent was designed by using methane to be the model of gas.This absorbent was composite micelle solution which compounded by anionic surfactant and nonionic surfactant.Anionic surfactant SDS（sodium dodecyl sulfate） was compounded respectively to be composite micelle aqueous solutions of certain concentration with nonionic surfactant TX-100、TW80、OP-7、EL-20、BS-12 in different proportion.The absorption effect to methane was determined by gas chromatography and quantitative compared.The composite micelle solution compounded by SDS BS-12 with the proportion 1：2.5 has the best absorption effect.The micelle size and aggregation of composite micelle solutions were analyzed by laser particle-size analyzer and the difference of absorption effect of different micelle solutions were analyzed.The results show that the absorption effect to methane of composite micelle solution is related to the space size of the micro-area of micelle kernel and the micelle solutions with better absorption effect have larger micelle size.
