The AB(2) type monomer, 2,2-bis (hydroxymethyl) propionic acid (bis-MPA), was successfully grafted from the surfaces of the amino groups modified attapulgite nano-fibrillar clay (A-ATP) via a melt polycondensation method with p-toluenesulfonic acid (p-TSA) as catalyst. The competitive adsorption properties of the hyperbranched aliphatic polyester grafted attapulgite (HAPE-ATP) towards the heavy metal ions (Cu(II), Hg(II), Zn(II), and Cd(II)) were investigated preliminarily.
通过以对甲苯磺酸（p-TSA）为催化剂的熔融缩聚法，成功地将AB(2)型单体2,2-双（羟甲基）丙酸（双-MPA）接枝到氨基改性凹凸棒石纳米纤维粘土（A-ATP）的表面。初步研究了超支化脂肪族聚酯接枝凹凸棒石（HAPE-ATP）对重金属离子（Cu(II)、Hg(II)、Zn(II)和Cd(II)）的竞争吸附性能。
