“…Sulaymon et al reported that larger ionic radius may result in greater adsorption efficiency [40]. The ionic radius of three metals was decreased in the following order: Pb>Cu>Ni [41]. The ionic radius of Pb may be closer to the space of metal binding sites in the cell wall, which may explain the selectivity of Pb.…”

With the dynamic development of industrialization and urbanization, the entrance of heavy metals from industrial discharge, domestic sewage, and atmospheric deposition into natural water, even at low concentrations, has induced a series of potential impacts on both aquatic ecosystems and human health [1]. Being an essential part of primary productivity, algae show high sensitivity to various heavy metals such as Pb [2]. Consequently, algae serve as a testing model to evaluate the quality of freshwater and estimate the toxicity of pollutants. By now, numerous studies have illustrated that most heavy metals, including Cd, Pb, Cu, and Ni, can interfere with the photosynthesis and enzymatic metabolism of algae, which results in growth inhibition and even death. Choudhary et al. found that Pb, Cu, and Zn could generate reactive oxygen species (ROS) and attack biomolecules within the cells, further leading to irreversible adverse effects on Spirulina [3]. The analogous toxic mechanism of Cu on the green Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThe link between the acute toxicity of heavy metals on algae and the bioadsorption capacity of heavy metals by algae has seldom been reported. In the present study, an acute toxicity experiment was carried out to assess the toxic effects of Pb, Cu, and Cd for Chlorella sorokiniana, and the 96 h IC 50 values were 0.249 mg/L, 0.485 mg/L, 46.108 mg/L, and 21.00 mg/L for Cu, Cd, Pb (total), and Pb (free ion), respectively, which implied that Chlorella sorokiniana showed high tolerance to Pb compared to Cu and Cd. Pb distribution analysis indicated that 73.40% to 98.15% of free Pb ions were accumulated on the algae cell wall to avoid further intracellular accumulation, resulting in irreversible metabolic disorders. Then the adsorption capacity of Chlorella was explored. It could be found that the Langmuir model (the R 2 were 0.988 and 0.962 for living and lifelss cells, respectively) was fit to explain the adsorption equilibrium data and the q e calculated by this model were 1.54 and 2.97 mg /10 10 cells for living and lifeless cells, respectively, which was consistent with the experimental result. In the competitive adsorption, Chlorella exhibited a greater affinity for Pb with the higher removal rate compared to Cu and Ni. Therefore, the renewable Chlorella sorokiniana and its dramatic resistance to Pb may serve as a potential biosorbent for Pb in the future.

“…The most widely used techniques for removing metal ions from wastewater include chemical precipitation, ion exchange, reverse osmosis and solvent extraction and adsorption [2][3][4][5][6][7][8][9][10][11][12][13][14]. Several studies have reported that significant amounts of heavy metals are removed from solution by adsorption on fly ash [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

Abstract:The removal of Cd 2+ , Zn 2+ and Ni 2+ by coal bottom ash has been investigated. In single metal system, metal uptake was studied in batch adsorption experiments as a function of pH (2-3), contact time (5-180 min), initial metal concentration (50-400 mg/L), adsorbent concentration (5-40 g/L), particle size, and ionic strength (0-1 M NaCl). Removal percentages of metals ions increased with increasing pH and dosage. Removal efficiency at lower concentrations was greater than at higher values. The maximum amount of metal ion adsorbed in milligrams per gram was 35.4, 35.1 and 34.6 mg/g for Zn 2+ , Cd 2+ and Ni 2+ , respectively, starting out from an initial solution at pH 3. Simultaneous removal of Zn 2+ , Cd 2+ and Ni 2+ ions from ternary systems was also investigated and compared with that from single systems. Cd 2+ uptake was significantly affected by the presence of competing ions at pH 2. The results obtained in the tests with landfill leachate showed that bottom ash is effective in simultaneously removing several heavy metals such as Ni, Zn, Cd, As, Mn, Cu, Co, Se, Hg, Ag, and Pb.

“…As resinas de troca iônica têm sido recomendadas como uma interessante opção para o tratamento de efluentes, pois se mostram eficazes na redução da concentração dos íons metálicos presentes [8] . A resina catiônica AMBERLITE IR 120®, por exemplo, apresenta grupos sulfônicos em sua superfície (-SO 3 H), nos quais íons H + podem ser trocados por outros cátions, removendo assim íons metálicos positivos por meio de uma reação de troca iônica.…”

Resumo: As resinas de troca iônica têm sido amplamente usadas como uma opção de tratamento de efluentes químicos por removerem do meio diversas substâncias, principalmente íons metálicos. Neste contexto, o objetivo do trabalho foi avaliar o potencial do uso de uma resina de troca iônica para o tratamento de um resíduo ácido contendo Fe 3+ , ânions metálicos e ácido salicílico. As condições experimentais foram otimizadas a fim de remover essas espécies de um resíduo regularmente gerado em um dos laboratórios de ensino da UFJF. Foi utilizada a resina catiônica AMBERLITE IR 120® e os resultados mostraram boa eficiência na remoção das espécies de interesse, inclusive daquelas na forma de ânions. Também foi estudado o processo de dessorção da resina, onde os metais podem ser concentrados em um volume 70% menor, possibilitando a reutilização da mesma.Palavras-chave: tratamento de resíduos, resina de troca iônica, íons metálicos, adsorção.
