“…3). The results obtained were comparable to the SEM results obtained by Rao and Ikram (2011) where the surface of sorbent after and before adsorption were compared for heavy metal Cu (II). This result is comparative to our SEM analysis study were we observed a decrease in pore size after adsorption.…”

“…Deposition of waste, high operating cost and environmental pollution are some of the limitations that exist. Biosorption proposes to be an efficient, economical and environment friendly technique for metal purification/removal in comparison to the conventional techniques (Rao and Ikram 2011). There are several criteria to be considered while selecting the materials to be used as a biosorbent directly or for the production of sorbent, the main criteria being the raw material availability (Oliveira et al 2008).…”

The sorption of Ni (II) metal using Indian gooseberry (Phyllanthus acidus) seeds was studied. The main objective behind carrying out this study was to test the metal removal efficiency of gooseberry seeds for a heavy metal such as Ni (II). The main parameters (kinetic data) included in this study were effect of pH, of contact time, initial metal concentration and dosage concentration studies. The optimum equilibrium found was at 90 min. The equilibrium data was well agreed with Langmuir, Freundlich and Harkins-Jura isotherm models. The adsorption system was found to follow the pseudo-second kinetics. The presence of functional groups and its corresponding effect on Ni (II) metal was observed using FTIR spectroscopy. SEM analysis was carried out to compare the intraparticle pore size of the sorbent material before and after adsorption. The study indicated that gooseberry seed powder activated using sulphuric acid (H 2 SO 4 ) proved to be a promising biosorbent for the removal of Ni(II).

“…At higher pH values, the lower number of hydrogen ion and greater number of ligands with negatives charges results in greater metal ions biosorption [33]. The maximum adsorption of metal ions is obtained at pH 5.0 [34], above pH 5, a steady decrease of adsorption of metal ions can be related to the precipitation of metal hydroxide [35,36]. Figure 7 presents the effect of different initial metal ions concentration onto UDL.…”

Abstract:The biosorption of Cu (II), Zn (II) and Pb (II) ions from aqueous solution onto dried biomass (Urtica dioica leaves) is discussed in the present study. The effect of variation of contact time, adsorbent dose, pH, concentration of metal ions and temperature on biosorption of metal ion is studied. Maximum adsorption was recorded for initial metal ion concentration of 10 mg/l, adsorbent dose of 2 gm, at pH 5 with 60 minutes of contact time for Lead and Zinc, 45 minutes of contact time for Copper ion. The equilibrium conditions were well described by Langmuir, Freundlich and Temkin isotherm equations. The Langmuir isotherm model have provided a better fit with the experimental data compared to that of Freundlich and Temkin isotherm models. The values of thermodynamic parameters indicate that the adsorption reactions were spontaneous, feasible and exothermic.

“…Many agricultural wastes have been tried out as effective and low-cost adsorbents for the removal of heavy metals from waste water. Many of the fruit peels and seeds have also been used as effective sorbents for the removal of heavy metals which include banana peel [7], mango peel [8], orange peel, citrus peel [9], jackfruit peel [10], ponkan peel [11], pomegranate peel [12], watermelon rind [13], gooseberry fruit [14], and pine fruit coat. Heavy metals such as Pb 2+ , Cd 2+ , Zn 2+ , Ni 2+ , Cr 6+ , and Cu 2+ are prior toxic pollutants in industrial wastewater, which become common groundwater contaminants and they tend to accumulate in organisms, causing numerous diseases and disorders [15].…”

A B S T R A C TAdsorbent prepared from Annona squamosa (custard apple) fruit shell (CAS) was successfully used to remove lead (Pb 2+ ) and cadmium (Cd 2+ ) from aqueous solution in a batch process. Adsorption studies were conducted on a batch process, to study the effects of contact time, initial concentration of metal ions, adsorbent dose CAS, pH and temperature. The optimum contact time and pH for the removal of Pb 2+ and Cd 2+ was 30 min and pH 5, respectively. Kinetic parameters of adsorptions such as pseudo-first order, pseudo-second order were determined. The maximum loading capacity of Pb 2+ and Cd 2+ was found to be 90.93 and 71.0 mg g À1 of the adsorbent, respectively. The equilibrium data were analyzed by the Langmuir and Freundlich isotherms. Langmuir model gives a better fit than the Freundlich model. The pseudo-secondorder kinetics was the best for the adsorption of Pb 2+ and Cd 2+ , by CAS (A. Squamosa) with good correlation. Thermodynamic parameters, such as standard free energy change (DG˚), standard enthalpy change (DH˚) and standard entropy change (DS˚), were analyzed. The results suggest that the CAS can be used as an effective, low cost, and eco-friendly green adsorbent for the removal of selected metal ions from aqueous solution.
