Adsorption of Nickel (II) by Silica from Rice Husk

M. K. Bhatnagar [6] | Awanish Patel [2]


Abstract: The removal of nickel ions from aqueous solution by adsorption on hybrid precursor was investigated. The Rice husk were obtained from Rice mills Shahdol. A Silica adsorbent derived from rice husk by nitric acid treatment was used for the removal of Ni (II) from aqueous solution. The solution of nickel was prepared of 1000 ppm & analyzed by AAS. Sorption of metal ion has been studied as a function of contact time, temperature, pH of the solution and metal ion concentration. These factors have remarkable positive effect on sorption process. The adsorption data of RHHP at different initial concentration was fitted to Freundlich & Langumuir adsorption isotherms and monolayer sorption capacity determined was 83.56 (pH 6.0 temperature 400c). Thermodynamic Parameter indicated that the sorption is exothermic, spontaneous with a greater affinity of metal species for the adsorbent.
