Abstract:
The giant reed (GR) was modified for the removal of phosphate by reacting with epichlorohydrin, ethylenediamine (EDA) and triethylamine. The factors influencing dynamic adsorption and desorption were investigated and the re-adsorption effects of phosphate were tested. The results showed that the adsorption capacity of the modified giant reed greatly increased much, compared with giant reed. A shorter breakthrough time was found in a higher concentration of phosphate and the phosphate removal in solution decreased with increasing flow velocity. The effective pH for phosphate removal was 5.0. The 0.01mol／L NaCl, HCl and NaOH solutions had good desorption capacities.
Key words: modified giant reed, phosphate, dynamic adsorption, dynamic desorption, adsorptive capacity, desorption rate
