Fe3O4 loaded chitin – A promising nano adsorbent for Reactive Blue 13 dye

Không đóng trình duyệt đến khi xuất hiện nút TẢI XUỐNG Tải xuống

The mechanism of dye-adsorbent interaction is described on the basis of zero-point charge and zeta potential techniques. Batch adsorption studies on MCH NM show excellent adsorption activity of 199.02 mg/g in 22 min towards RB13 dye, maximum value ever reported for any reactive dye. Equilibrium adsorption data and adsorption kinetics were well fitted into Langmuir isotherm model and pseudo second order model predicting chemically rate controlled monolayer adsorption. |
