Abstract:In the work, adsorption of Cu 2+ ions onto almond shell were investigated under different operational conditions. Almond shell was used without any pretreatment prior to the tests. The optimum conditions for adsorption of Cu 2+ ions through almond shell were determined to be; pH 5.0, temperature 20ºC, shaking rate 125 rpm, sorbent dose 0.3 g and initial Cu 2+ ion concentration 50 mg/dm 3 . The equilibrium duration of the system was 60 minutes. The sorption capacities of the sorbents were predicted with the aid of equilibrium and kinetic models. The interactions of peanut shell with metal ions were constituted by SEM, EDX, FT-IR, XRD and AFM. The pseudo-first-order, pseudo-second-order, Weber-Morris, Elovich model and Bangham kinetic models were applied to test the experimental data. The Cu +2 ions adsorption onto almond shell was better defined by the pseudo-second-order kinetic model, for initial pH. The equilibrium data were evaluated using Langmuir, Freundlich, Temkin, D-R and Harkins Jura isotherms. The highest R 2 value in isotherm studies was obtained from Langmiur isotherm (R 2 = 0.98) for the inlet concentration.

In the present study, pummelo peel pretreated with sodium hydroxide is used for adsorption of methylene blue (MB). In order to investigate the effects of pretreatment on the cationic dye adsorption, the kinetics and capacities of raw pummelo peel (RPP) and sodium hydroxide treated pummelo peel (TPP) to remove MB from aqueous solutions were compared. The effects of various experimental parameters (e.g., initial pH, dye concentration, contact time) were also studied. According to the maximum adsorption capacity (q m ) obtained, adsorption capability of pummelo peel is significantly increased after sodium hydroxide treatment. Both adsorption isotherms of RPP and sodium hydroxide TPP fitted the Langmuir model well, but not the Freundlich model. The processes of uptake followed pseudo-first order rate kinetics. The results in this study indicated that sodium hydroxide TPP is a promising adsorbent for removing MB from aqueous solution.

“…At the optimum shaking time, it is expected that the adsorbent/adsorbate system has reached equilibrium, and hence, Hameed et al (2008) there would be no significant effect of settling time. This was experimentally proven by observing a constant extent of removal determined at the optimum shaking time during a settling time period increased up to 240 min for both dyes on each biosorbent.…”

The purpose of this research is to investigate biosorption characteristics of two cationic dyes, methylene blue (MB) and methyl violet 2B (MV), on breadfruit (Artocarpus altilis) peel and core. Characterization of breadfruit waste was conducted using surface titrations, thermogravimetry, and Fourier transform infrared spectroscopy. The extent of interaction between dyes and each biosorbent was monitored by absorbance measurements, which was then used in isotherm, thermodynamics, and kinetics analysis. Biosorption of MB and MV on breadfruit peel and core reaches equilibrium in 150-180 min. All four systems under investigation (MB-breadfruit peel, MB-breadfruit core, MV-breadfruit peel, and MV-breadfruit core) show similar extent of dye removal of about 80% under the conditions employed. Biosorption of both dyes on both biosorbents follow the Langmuir adsorption isotherm model at the ambient pH, at which the breadfruit surface bears a negative charge. Kinetics of biosorption of MB on breadfruit waste is so fast that it is not possible to determine the order of adsorption kinetics at the concentration level employed. The rate of biosorption of MV on breadfruit waste is smaller and follows pseudo second order kinetics with rate constants of 153.5 and 31.7 g mmol −1 min −1 for peel and core, respectively. Thermodynamics studies conducted for each biosorption system provide negative ΔG Θ , ΔH Θ and ΔS Θ values with the maximum biosorption for MB at the ambient temperature of 24 °C, while that for MV is obtained between 40 and 50 °C. All four biosorption systems show spontaneity and exothermic behaviour to varying degrees.
