Na+, Mg2+ and Ca2+ can increase the apparent solubility of CB in the surfactant. Thus, it can be seen that the mixed surfactant can prove to be able to greatly enhance the resistance to hard water and heighten the solubilization effect.

• Na+、Mg2+和Ca2+能增大氯苯在表面活性剂中的表观溶解度,阴非离子表面活性剂SDS与TW80混合后能提高表面活性剂的抗硬水能力,提高增溶效率。
