Abstract
The paper presents the adsorption abilities of organic material against manganese(II) ions. High concentrations of manganese ions cause serious damage to the environment thus novel methods for its removal are needed. The objective of the study is to use safe and natural by-product beet pulp shreds (BPS) as an adsorbent for the Mn ions adsorption from aqueous solutions. Equilibrium studies were performed to check the maximum sorption capacities of BPS against Mn ions. Kinetic calculations were used to obtain information on the effectiveness of the adsorption process. The speed, efficiency of this process were influenced by such parameters as contact time and metal ions concentration. Additionally, the influence of temperature on the course of the adsorption process was determined. Microbial studies of the BPS were performed and it was shown that there are yeast cells present in the material which in the temperature range of 20°C–30°C is characterized by their higher activity. Maximum sorption capacity for used temperatures (20°C–60°C) ranged from 4.692 to 6.800 mg/g respectively. Pseudo-second-order model, which assumes that the adsorption process is probably a chemical reaction provides the best fit.
