Abstract
The removal of any pollutant by Commercial Activated Carbon is highly practiced one. But in this study, manganese (II) ions by adsorption on Prosopis Juliflora Carbon (PJC) and comparison with Commercial Activated Carbon (CAC) have been made at 30±1°C under batch mode. The removal data on the variation of (i) initial concentration of manganese (II) ions, (ii) initial pH of the solution are determined, (iii) amount of material and (iv) contact time. The percentage removal of manganese (II) ions increased with the decrease in initial concentration and increased with the increase in contact time, the amount of adsorbent (PJC and CAC) and initial pH of the solution. Adsorption data have been analyzed with the help of adsorption kinetics. The observed RL value is 0-1 (0.102) and the correlations of log q vs log (dose) are also found to be linear with r-value close to unity (r value = 0.946 and 0.979) and after 90 minutes of contact time, the increase in the percentage removal of Mn (II) ions is not significant. The limiting factor involved in the study is intraparticle diffusion. In the current research it is found that PJC could be used as an alternate adsorbent material in the removal of metal ions, in general and manganese (II) ions, in particular.
