Abstract
The naturally occurring zeolite (N Z01) was characterized and used as an adsorbent for the removal of ammonium (N-NH4+) from water. The characterization results show that the NZ01 is mainly composed of clinoptilolite, quartz and plagioclase and has the cation-exchange capacity (CEC) of 64 cmol/kg. Batch adsorption results show that the best ammonia removal was at pH close to that of the natural water (= pH 7). The increase in initial ammonium nitrogen concentration from 5 to 50 ppm resulted in an increase of the adsorption capacity from 0.64 to 15.1 mg NH4+-N/g. The Jar test experiments indicate the introduction of the NZ01 enhanced the ammonium removal efficiency. All these results demonstrate that the NZ01 is potential to be used for the removal of ammonium in drinking water treatm ent process.
