摘要: 研究了阳离子表面活性剂十六烷基二甲基烯丙基氯化铵(CDAAC)在Al(OH)₃/水、CaCO₃/水界面上的吸附，探讨了无机阴离子对吸附量及表面电荷的影响，测定了样品的接触角和比表面。结果表明PO^3-₄的加入可提高Al(OH)₃、CaCO₃表面负电荷，有利于吸附，经吸附改性后的样品具有憎水性。

Abstract: In this paper, adsorption of cationics cetyl dimethyl allyl ammonium chloride (CDAAC) on Al(OH)₃ and CaCO₃ particles were studied. The effects of adding inorganic anion on adsorption amount and interface charge were investigated. The specific surface areas and contact angles of samples were determined. The results showed that adding PO^3-₄ was favourable to adsorption account for increasing interface negative charge, modification samples were hydrophobic.
