Adsorption characteristics on ammonia nitrogenof a new low cost adsorbent |
| |
| Abstract: | Adsorbent was prepared from Cyperus alternifolius as the raw material, and the removal effects of ammonianitrogen adsorption time, dosage, adsorption temperature, pH and particle size in different concentrations of carbonizedCyperus alternifolius were studied. Fourier Transform Infrared was used to detect and analyze the variation of functionalgroup before and after the treatments of ammonia nitrogen. The experimental results show that: with increasingcarbonization time, carbonization temperature, ammonia nitrogen removal rate reached maximum of 100%. The optimumconditions were: the adsorption time 60 min, adsorbent dosage 1.50 g, adsorption temperature 30, pH 6~8 and waterbamboo particle size 420~841 m. The results of Fourier Transform Infrared showed that abundant hydroxyl radical andamino -groups were found in carbonized Cyperus alternifolius, which reacted with ammonia nitrogen in wastewater toremove it. |
