Directly discharge of domestic laundry wastewater into surface water lead to a large amount of pollution in major proportion of linear alkyl benzene sulphonates ( LAS ). 家庭洗衣废水直排水体给城市河道带来了阴离子表面活性剂(LAS)的污染。
Using fatty acid methyl ester as the raw materials to produce fatty acid methyl ester sulfonate ( MES ) to instead of linear alkyl benzene sulfonate which is used in the detergent powder, becoming a new hotspot. 利用脂肪酸甲酯为原料生产脂肪酸甲酯磺酸盐(MES)代替直链烷基苯(LAB)磺酸盐用在粉状的洗衣粉中,成为新的研究热点。
Improvement of Equipment and Process in the Distillation System of Linear Alkyl Benzene(LAB) 直链烷基苯(LAB)分馏系统设备和流程的改进
Study on The Properties of Linear Alkyl Benzene(LAB) Sulfonate Combined With Different Counterion 结合不同反离子的直链烷基苯(LAB)磺酸盐性能研究
Chromium ion was separated from water by using the ferrous coprecipitation foam separation method. The influences of pH value, the molar ratio of Fe ~ 2 + to Cr (ⅵ), the concentration of a linear alkyl benzene sulfonate ( LAS ) and gas liquid ratio were investigated. 采用铁盐共沉淀泡沫分离法对水中的铬离子去除进行了研究,考察了pH值、Fe2+/Cr(Ⅵ)摩尔比、十二烷基苯磺酸钠(LAS)浓度、气液比等因素的影响。
