Arsenic poisoning and its removal from drinking water has become a serious issue now a days.
For arsenic removal batch studies were conducted using low cost adsorbent (raw date seeds husk and lemon
juice microwave activated date seeds husk) by taking 25ppm/50ml initial concentration of NaAsO2
. Best
removal (90%) was achieved for Lemon juice microwave activated date seed husk LMDS (time= 30mins,
agitation speed= 150 rpm, pH= 5, adsorbent dose= 0.1 g). While 85% removal efficiency was observed for
Raw date seed husk RDS (time= 45mins, agitation speed=250 rpm, pH= 4 and adsorbent dose= 0.5 g). The
adsorption isotherms (Freundlich and Langmuir) and adsorption dynamic kinetic studies were also conducted.
The comparison between the FTIR, EDX and SEM of RDS and LMDS revealed that with lemon juice
microwave activation of adsorbent there were activation of more active sites which in turn increased the
removal efficiency
