摘要
本文研究了表面活性剂对氢氧化镁吸附硼的影响,对不同类型的表面活性剂,不同的加入方式以及不同的加入量等进行了试验,并试验了在表面活性剂存在下,pH值对吸硼量的影响。阴离子表面活性剂——十二烷基硫酸钠的加入 可以减少Mg(OH)_2对硼的吸附;十二烷基硫酸钠加入的顺序对Mg(OH)_2吸硼没有影响,这表明Mg(OH)_2吸硼是可逆的;在十二烷基硫酸钠的存在下,最大吸硼量时的pH为10.3。
Effect of surfactant on boron adsorption from seawater on Mg(OH)2 surface was studied. Some influencing factors on boron adsorption were investigated such as types, adding order and amount of surfactant. Sodium lauryl sulphate can reduce boron adsorption. Adding order of surfactant has no effect on boron adsorption. It has shown that boron adsorption on Mg(OH)2 surface was. reversible. In the presence of sodium lauryl sulphate, maxium adsorption occured at pH 10.3.
