- Abstract
A latex sponge is modified by chitosan, tannic acid, and silane coupling agent KH550 to prepare an oleophobic sponge adsorbent, which can adsorb different kinds of charged dyes and Cu2+. The static adsorption capacity of the latex sponge before and after modification to methyl orange (MO) (negative charge), rhodamine B (RB) (neutral), methylene blue (MB) (positive charge), and Cu2+ under different initial concentration, pH, and reaction temperature are investigated, and simulations of adsorption kinetics and isotherms are performed. The modified latex sponge improves the overall adsorption capacity along with the initial concentration and increases reaction temperature. The adsorption capacity of the adsorbent expands; when the pH is low, it is beneficial to adsorb MO and RB, and when the pH is high, it is favorable for the adsorption of MB and Cu2+. Adsorption kinetics and isotherm data show that the isotherm dates of pure latex sponge conform to the Langmuir isotherm model, while the isotherm dates of modified latex sponge conform to the Freundich isotherm model; however both of them are more fitted with the pseudo‐second‐order adsorption model, and the chemical adsorption is the main one.
