“…This dehydration energy exceeds the exothermicity of the ion attaching to the surface. The dissociation of water from ions is essentially an endothermic process that exceeds the enthalpy of sorption to a considerable extent [33,58,59].…”

A B S T R A C TBioremediation is a low-cost eco-friendly separation technique for the treatment of pollutants such as heavy metals and organics from wastewaters. In the present study, a biosorbent, Lonicera japonica flowers powder (LJFP) was prepared from Lonicera japonica flowers (LJF) for treating Pb (II) and Co(II) from aqueous solutions and was well characterized by FT-IR and SEM-EDX. The kinetic results showed that the kinetics of both metal ions was rate limiting pseudo-second order. However, Pb(II) was also involved in chemisorptions, which was proved by the Elovich kinetic model. The equilibrium data of Pb(II) were tuned with Langmuir isotherm whereas Co (II) was fit to Freundlich isotherm model. The maximum uptake capacities of LJFP for Pb(II) and Co(II) were 19.61 and 43.48 mg/g at 298 ± 2 K, pH 6.0. Thermodynamic studies were conducted in the range of temperature, 298-313 ± 2 K, and were revealed that the sorption process of Pb(II) and Co(II) on LJFP was endothermic. Overall studies demonstrated that the biomass, LJFP is a promising, efficient, economical, and reusable sorbent.

“…Esta banda é larga e forte (Figura 1) por causa do elevado número e grande densidade de ligações de hidrogênio, principalmente hidroxilas nos anéis polissacarídeos da piranose (Oliveira et al, 2014). O espectro de FTIR mostra um pequeno deslocamento da banda, o que pode ser correlacionado com a interação de íons de cobre e zinco com os grupos -NH2 (Subbaiah et al, 2011).…”

RESUMO -A capacidade natural de troca catiônica da macroalga Pelvetia canaliculata foi investigada para a remoção dos metais Cu 2+ e Zn 2+ de soluções aquosas. Através das técnicas de FTIR e de titulação potenciométrica foi possível determinar que os principais grupos funcionais presentes na superfície da alga responsáveis pela ligação dos metais são os grupos sulfônicos e carboxílicos, representando no total 2,5 mEq/g. Os ensaios de esterificação da biomassa permitiram a quantificação dos grupos sulfônicos (1,0 mEq/g) e grupos carboxílicos (1,5 mEq/g). Os coeficientes de seletividade de cobre ou zinco vs hidrogênio foram muito menores do que com o sódio, indicando que os íons de hidrogênios podem competir pelos mesmos sítios de ligação, diminuindo fortemente a remoção dos íons de cobre e zinco em baixos valores de pH. A pH 4,0 quase todos os sítios ativos presentes na superfície da alga foram ocupados pelos íons cobre ou zinco (∼2,4 mEq/g). INTRODUÇÃOO meio mais usual de contaminação por íons metálicos é através da descarga de efluentes não tratados em ambientes aquáticos. A liberação desses compostos deve-se em grande parte pelas indústrias de mineração, fundição, processamento de minérios, fabricação de equipamentos elétricos, têxtil, couro, baterias, fertilizantes, pesticidas, entre outras (Volesky, 2001). Os íons de cobre e zinco estão entre os metais pesados mais comuns presentes nestes tipos de águas residuárias.Tendo em vista a importância do controle da poluição da água, um grande número de tecnologias tem vindo a ser desenvolvidas para remover metais tóxicos dos efluentes industriais. Entre essas tecnologias, a biossorção vem ganhando destaque nos últimos anos, pois apresenta como vantagem a utilização de biomassa existente em quantidades abundantes, como por exemplo, algas ou resíduos de outras operações industriais (Volesky, 2001).A elevada capacidade de remoção de íons metálicos por algas marinhas é devido à presença de vários grupos funcionais na superfície das algas, tais como grupos carboxílicos e sulfônicos. Entre os diferentes tipos de algas, as algas marrons tem provado ser um ótimo biossorvente para remoção de Área temática: Engenharia Ambiental e Tecnologias Limpas 1

“…1,2 Cadmium, lead, and copper, whose toxicities and limit values are shown in Table I, were chosen as models in this study because of their solubility over a wide range of pH values and their presence in much industrial wastewater. 3,4 Because of the toxicity and persistence in the environment of heavy metals, a variety of treatments have been developed; these include chemical reduction, oxidation, reverse osmosis, electrochemical treatments, ion exchange, precipitation, flocculation, membrane filtration, and adsorption (physisorption, chemisorption, and biosorption). 5 Among them, adsorption is considered one of the most efficient and promising methods for the treatment of trace amounts of heavy-metal ions from large volumes of water because of its high enrichment efficiency, high costeffectiveness, and ease of phase separation.…”

A silica‐sphere–poly(catechol hexamethylenediamine) (PCHA–SiO2) composite was prepared via the one‐step facile polymerization of catechol and hexamethylenediamine; this method uses a silica sphere as a hard template. The chemical structures and morphologies of this composite were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, and transmission electron microscopy. The adsorption experiments indicated that the PCHA–SiO2 composite served as a very attractive adsorbent for Pb(II)‐, Cu(II)‐, and Cd(II)‐ion removal at lower concentrations and had very good selective adsorption abilities for Pb(II) and Cu(II) ions in a solution contaminated with these three ions at higher concentrations. These interesting results may have been due to the reversible H+ adsorption–desorption properties of the characteristic phenol amine structure of the PCHA–SiO2 composite. © 2017 Wiley Periodicals, Inc.
