摘要：

The feasibility of using honeycomb-cinder slag as an adsorbent for phosphate removal from aqueous solution was investigated in batch experiments as a function of initial pH, contact time, adsorbent dose, and solution temperature. The results indicated that the solution pH significantly influenced the phosphate adsorption; 1440 min was enough to reach equilibrium for any concentration. Langmuir isotherm model gave well fit for phosphate adsorption, and the adsorption process followed pseudo second-order model. Desorption study exhibited that the phosphate adsorption on the honeycomb-cinder slag is not completely reversible. Results showed that honeycomb-cinder slag could be used as an adsorbent to uptake phosphate from wastewater.
