AB  - This study is aimed to evaluate the possibility of lemon peel, as an agro-industrial waste, to remove Fe2+, Zn2+ and Mn2+ from single aqueous solutions and mining wastewater. For this purpose, the influence of various parameters: sorption time, initial pH solution, initial metal ion concentration and a dose of sorbent on the sorption process were studied in batch experiments. The experimental equilibrium data have been analysed utilizing linearized forms of Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms. The Langmuir isotherm provided the best theoretical correlation of the experimental equilibrium data for Fe2+, Zn2+ and Mn2+, with the maximum sorption capacities of 4.40, 5.03 and 4.52 mg g(-1), respectively. The percentage of targeted ions removal from single aqueous solutions was 92.9 % (Zn2+), 84.5 % (Fe2+) and 78.2 % (Mn2+). Regarding the sorption capability of lemon peel in mining wastewater, the maximum removal of Fe2+, Zn2+ and Mn2+ from mining wastewater was 49.62, 33.97 and 9.11 %, respectively. In addition, the potential reusability of the lemon peel as sorbent was investigated through desorption study in 0.1M of CH3COO4, HCl and HNO3 solution. The highest rate of desorption was achieved in 0.1 M HCl solution, reached a value of 55.19 % for Mn2+ and 37.24 % for Zn2+, while for Fe2+ the highest value of 25.82 % was achieved in 0.1M HNO3 solution.

AB  - New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate phase had better compatibility with agar matrix than Cu-phosphate phase. Incorporation of both mineral phases improved mechanical and water vapor barrier properties of the obtained mineralized films, in concentration dependent manner. When 5 mM of carbonate precursor was incorporated into agar matrix, mechanical resistance was enchanced for 44% and water vapor barrier property for 40%. The release of Cu (II) was higher in acidic conditions for both mineralized composites and remained in the range of specific release limits for this metal. In addition, both mineralized composite films exhibited distinctive antimicrobial activity against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria. Overall, the Cu-carbonate and Cu-phosphate mineralized agar films showed potential to be used for food packaging materials, agriculture or medical purposes.

AB  - In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion concentration and dose of adsorbent on sorption were studied in batch experiments. The maximum Langmuir adsorption capacity was evaluated to be 13.2 mg/g at optimum contact time of 15 min. The maximum removal of copper ions from mining-wastewater at natural pH (pH3) was 89%, indicating that lemon peel could be employed as an effective low-cost adsorbent for removal of copper ions from wastewater at acidic conditions.
