Removal of Ni (II) From Aqueous Water Using A Mixture (50: 50) of Bentonite and China Clay As An Adsorbent
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 3
Abstract
Abstract: Waste water contains heavy metals as toxic pollutants; Nickel is one of them which need to dispose carefully in the environment. A potential adsorption of nickel from various aqueous solutions was performed. Parameters such as pH, interaction of different cations like K(I), Na(I), Mg(II), Ca(II), contact speed RPM; contact time and the concentrations of adsorbent and adsorbate were studied to optimize the conditions to be utilized on a commercial scale for the decontamination of effluents using a batch adsorption technique. Adsorption parameters were determined using Langmuir isotherm. The optimum pH for nickel removal was 6, the percentage of nickel removal at equilibrium increases with increasing the amount of wastes. The removal of Ni(II) ions attained 74-77 %., this means that Ni(II) can be effectively removed from aqueous solutions by wastes. The mechanisms for adsorption of Ni(II) ions from wastes involved complex formation of nickel with rubeanic acid which was estimated spectrophotometrically.
