Original Abstract
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 used for 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 found that 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 of arsenic(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 theendothermic spontaneous and a physisorption process.
