“…For many years, S. cerevisiae has been studied as a biosorbent of organic compounds such as dyes (Mahmoud, ), pesticides and herbicides (Tunçeli et al ., ), as well as of inorganic compounds such as metals (Hadiani et al ., ; Zheng et al ., ). However, a new application of S. cerevisiae as a biosorbent of secondary metabolites from industrial waste has recently emerged, demonstrating that this approach is promising for the recovery of biocompounds (Stafussa et al ., ; Rubio et al ., ).…”

The residual Saccharomyces cerevisiae from brewing was used as a biosorbent of flavonoids of hydro alcoholic extract from samples of grape pomace (Merlot and Tannat). Biosorption assays verified that the pseudo-second order kinetic model and the Dubinin-Raduschkevich isotherm model presented the best fit, with free energy of adsorption (E) of 7.1 and 6.5 kJ for the Merlot and Tannat varieties, respectively, indicating that the yeast has many binding sites and adsorption was a physical process. The analysis of microscopy and spectroscopy showed differences in structure and composition of the yeast after biosorption, demonstrating that the application was effective, which was confirmed by the chromatographic analysis, where a reduction in 17% and 50% in the catechin peak was observed in the Merlot and Tannat samples, respectively. Finally, there was an increase in the in vitro bioaccessibility of flavonoids in 68% for the Merlot sample and 88% for Tannat, reaching the main objective of this application. Determination of biosorption kineticsAs described by Stafussa et al. (2016), to perform biosorption kinetics, 125 mL Erlenmeyer flasks containing 50 mg of yeast S. cerevisiae (dry weight), and 12.5 mL of solution of grape pomace hydroalcoholic extract were used. The flasks were shaken at 130 r.p.m. and 25°C, and samples were taken at

According to Hadiani et al . the decrease occurred due to a split in the flux or the concentration gradient between the amount of Pb(II) present in the solution and that on the biosorbent surface; where it may cause reduction of Pb (II) biosorption capacity (in unit weight of biosorbent).…”

According to Hadiani et al 16 the decrease occurred due to a split in the flux or the concentration gradient between the amount of Pb(II) present in the solution and that on the biosorbent surface; where it may cause reduction of Pb (II) biosorption capacity (in unit weight of biosorbent). Moreover, a partial aggregation of biosorbent at larger biosorbent doses could also lead to a decrease in the effective surface area for biosorption resulting in a biosorption capacity reduction 46 .…”

“…11,13,14 The main aim of the present study was (1) to introduce a common durian waste as a precursor sorbent and prepare productive biosorbent in the form of activated carbon which is efficient for Pb(II) removal from contaminated aqueous phase, and (2) to establish the interactions of pH, initial Pb(II) concentration, biosorbent dose, temperature and contact time to achieve maximum adsorption capacity. A face-centred central composite design (FCCCD) method was adopted for optimization of the process parameters, 15,16 i.e. pH of the solution, DHAC dose, contact time, reaction temperature and initial Pb(II) ion concentrations.…”

Background Biosorption of lead Pb(II) by durian husk activated carbon (DHAC) was investigated. The main aim of this work is to explore the effect of operating variables such as pH, biosorbent dose, temperature, initial metal ion concentration and contact time on the removal of Pb(II) from synthesized aqueous medium using a response surface methodology (RSM) technique. The experimentation was performed in two sets, namely set 1 and set 2. Results For experimental set 1, pH was set to 7.0. The optimum conditions for the remaining parameters were determined to be 0.39 g DHAC dose, 60 min contact time and 100 mg L−1 of initial metal ion concentration, which yielded maximum biosorption capacity of 14.6 mg g−1. For experimental set 2, 41.27 °C, 8.95 and 99.96 mg L−1 were the optimum conditions determined for temperature, pH and initial Pb(II) concentration, respectively; which revealed a maximum adsorption capacity of 9.67 mg g−1. Characterization of the adsorbent revealed active functional groups such as hydroxyl, carboxylic, alcohol and hemicellulose. The equilibrium adsorption data obeyed the Langmuir isotherm and pseudo‐second‐order kinetic models with maximum Langmuir uptake of 36.1 mg g−1. Conclusions The biosorbent was capable of reuse, so that the abundant durian husk could be utilized effectively for the removal of Pb(II) from polluted water. © 2018 Society of Chemical Industry

“…Various techniques have been proposed to get rid of lead ions from aqueous phase system. Chemical oxidation and reduction, coagulation‐sedimentation, solvent extraction, precipitation, membrane filtration, reverse osmosis, and ion exchange are the most widely used techniques for removal of bivalent ions from water (Hadiani, Darani, Rahimifard, & Younesi, ; Kaur, Mandiyal, Singh, Kumar, & Chawla, ; Kumar & Chawla, ; Kumar, Chawla, & Kaur, ; Kyzas, Deliyanni, & Matis, ; Zhao et al, ). The main drawback of conventional technologies is the production of toxic sludge and ineffectiveness at low concentrations.…”

Punica granatum carpellary membrane powder (PGCM) and its surface modified form (MPGCM) with 2,4‐dinitrophenylhydrazine (2,4‐DNP) were used as adsorbents for removal of bivalent lead ions from aqueous phase system. Batch mode experiments using various parameters were carried out to assess the adsorption isotherms and dynamics of the process. Langmuir isotherm was well‐fitted model for experimental data. Langmuir adsorption capacity using PGCM and MPGCM at pH of 7 was found to be 169.49 and 196.07 mg/g, respectively. Rate constant and thermodynamic parameters were calculated to evaluate the kinetic model and temperature dependence nature of adsorption. Box–Behnken design was applied to optimize the adsorption process of bivalent lead ions for PGCM and MPGCM using pH (3.0–9.0), initial bivalent lead ions concentration (20–100 mg/L), contact time (20–180 min), and temperature (20–60°C) parameters. The optimum conditions for maximum removal of bivalent lead ions on PGCM were found to be at pH of 6.99, initial bivalent lead ions concentration of 98.95, contact time of 176.05, and temperature of 21.20°C and on MPGCM at pH of 6.51, initial bivalent lead ions concentration of 99.99, contact time of 177.89, and temperature of 20.02°C, respectively. Practitioner points Adsorption of bivalent lead from water using Punica granatum carpellary membrane powder and its modified form MPGCM is discussed. Batch mode experiments using various parameters were carried out to assess the adsorption isotherms and dynamics of the process. Langmuir adsorption capacity using PGCM and MPGCM at pH of 7 was found to be 169.49 and 196.07 mg/g, respectively. Box–Behnken design was applied to optimize the adsorption process of bivalent lead ions.
