A Comparative Study: Adsorption Behavior of Different Nickel (II) Salts on to Alkaline Soil
Deepak Hada | Shweta Saxena 
Abstract: Ni(II) is one of many heavy metals that are present in the environment. The impact of heavy metals on the soil environment is determined by the soil's ability to immobilize these pollutants. From the viewpoint of soil stabilization, it is essential to look at how heavy metals and soil interact. A range of experiments were used in this study to investigate the adsorption behavior of different Ni(II) compounds [NiCl2, NiSO4 and Ni(NH4)2(SO4)2] in alkaline soil. Soil is used as an adsorbent for Ni(II) removal from aqueous solutions. The experimental results were tested in a batch mode to analyze adsorption characteristics like PH, amount of adsorbent and initial concentration of metal ions. The change in Ni (II) concentration due to adsorption was determined by the dimethylglyoxime spectrophotometric method. Maximum nickel adsorption occurred at an initial metal ion concentration of 4 mg/L, an amount of soil of 6 mg/50 ml, and pH of 10. The equilibrium time was 14 minutes. Under ideal conditions, the absorption spectrum of the Ni(II)-DMG complex was scanned with a visible spectrophotometer ((?= 445 nm). This study aims to quantify whether the adsorption of Ni on soil is important for evaluating the data on nickel functioning in farm soil. The results indicated that alkaline soil of a farm site can be used as an effective and low-cost adsorbent to remove nickel ions from aqueous solutions.
