Description
ABSTRACT Porous amine-modified MCM-41/Nylon-6 nanocomposite (NH 2-MCM-41/NY6
NC) was synthesized by a facile solution casting protocol, which was used as an effective
adsorbent for the removal of Cu (II) and Cd (II) from aqueous media. The physicochemical
properties of NH 2-MCM-41/NY6 NC were studied by scanning and transmission electron
microscopies, thermogravimetric analysis, etc. The influence of pH, adsorbent dose, contact
time and initial concentration on adsorption performance were investigated in detail. Kinetic
and isotherm parameters were evaluated and the data fitted well to the pseudo-second
order and Freundlich isotherm model, respectively. The maximum adsorption capacities of
Cu (II) and Cd (II) were about 35.84 and 27.5 mg· g− 1, respectively. The K d of NH 2-MCM-
41/NY6 NC for Cu (II)(> math formula
