Adsorption of arsenic by activated carbon, calcium alginate and their composite beads
Original language description
The present investigation deals with preparation of three different adsorbent materials namely; potas-sium hydroxide activated carbon based apricot stone (C), calcium alginate beads (G) and calciumalginate/activated carbon composite beads (GC) were usedfor the removal of arsenic. The prepared adsor-bent materials were characterized by scanning electron microscope (SEM), Fourier transform infraredspectroscopy (FTIR), N2-adsorption at 196 C and point of zero charge. From the obtained results, itwas foundthat the porosity, surface area and total pore volume of the adsorbent material C > GC > Grespectively, however, the G adsorbent has more acidic function group than the other adsorbents. Theinfluence of pH, time, temperature and initial concentration ofarsenic(V) were studied and optimized. GCexhibits the maximum As(V) adsorption (66.7 mg/g at 30 C). The adsorption of arsenic ions was observedto follow pseudo-second order mechanism as well as the thermodynamic parameters confirm also t
