Silica aerogel is a kind of nanoscale amorphous solid mesoporous material made by agglomerating colloidal particles with gas as dispersion medium, providing silica aerogel with high surface area and absorptive performance. The humics contain a large number of carboxyl which brings a strong adsorption behavior for Cu(II). The morphology and structure of the as-prepared silica-humics composite aerogels were prepared via sol-gel method. In this paper, the adsorption behavior of 10 mg/L Cu(II) to silica-humics composite aerogels was studied. The adsorption parameters such as pH, temperature and the amount of silica-humics composite aerogels were studied to achieve the optimal conditions. This work opens a new perspective for the Cu(II) removal from contaminated water.
