Title

NATURAL ADSORBENT PREPARED TO ELIMINATION OF HEAVY METAL FROM SPIKED SOLUTIONS – BATCH MODE STUDY

Abstract

To study the effects of pH on the adsorption of Cr (VI), experiments were carried out using 100 mg of the adsorbent in 50 ml solution of 10 mg / lit of Cr (VI) concentration, adjusted to different pH values ranging from 2.0 to 9.0 using 0.1N H2SO4 and 0.1N NaOH solutions . The solutions after equilibrium for a period of 120 minutes were centrifuged. The centrifugates were tested for Cr (VI) concentration spectrophotemetrically APHA 1995. The results are shown in Table – 1, maximum adsorption is 96.50. The high adsorption capacity of Cr (VI) in the lower pH range is due to protonation of adsorbent surface, which would favour the uptake of anionic forms HCrO4-1 and CrO4-2. Many authors have observed adsorption increases with decrease in pH for Cr (VI) removal. Dahe Fan et al., (2006) reported maximum adsorption of Cr (VI) at pH 4.0 by Chitosan coated montmorillonite. With the increase in pH of the system, the degree of protonation of the surface is reduced gradually and hence decreased the adsorption. Similar trend has been observed for the removal of Cr (VI) by Fe (III) / Cr (III) hydroxide (Namasivayam and Ranganathan, 1993).
