“…In comparison with batch studies, there have been few dynamic biosorption studies [9]. Although a number of investigations have been carried out in fixed-bed arrangement on the adsorption of Cu(II) ions onto coconut-shell [10], chitosan immobilized on bentonite [11], zeolite/cellulose acetate blend fiber [12], rice husk-based activated carbon [13] to name a few. Similarly, Ni(II) ions sorption was studied onto activated carbon obtained from sugarcane bagasse pith [14] and tea factory waste [15].…”

A B S T R A C TFixed-bed column studies were performed using magnetized sawdust (Fe 3 O 4 -SD) as adsorbent for removal of Cu(II) and Ni(II) ions form aqueous solutions. Breakthrough curves were obtained by performing experiments in order to evaluate the influence of adsorbent bed height (2, 4, 8 cm), metal ion concentration in feed solution (10, 20, 30 mg/L), and feed flow rate (15, 20, 25 mL/min) for adsorption of Cu(II) and Ni(II) ions onto Fe 3 O 4 -SD adsorbent. Adsorption kinetics was analyzed using Bohart-Adams, Thomas, and Yoon-Nelson models. Kinetic data correlated well with both Thomas and Yoon-Nelson models, while Bohart-Adams model poorly predicted the model operation. Saturation loading capacity of adsorbent bed decreased with increase in adsorbent bed height, metal concentration in feed, and feed flow rate. Both mass transfer zone (MTZ) height and height of unused bed (H UNB ) noticeably increased with increase in the values of the parameter studied. The results showed that reduced MTZ height and lowest H UNB are suitable for operating the column satisfactorily.

The commonly used removal processes for heavy metals from contaminated wastewater and cited in the literature are chemical precipitation, electrowinning, carbon adsorption, reverse osmosis, preconcentrations, biosorption, phytoremediation etc. Among these, biosorption is comparatively efficient, low cost, economical and reliable process. Actually, the reliability of the process is depending on the choice of local biosorbents and their abundant availability. The waste plant leaves of Kafal were collected from the region of Kumaun hills of India. The paper explains that the Kafal leaf powder is a good biosorbent for the removal of Cu (II) ions from contaminated wastewater under batch study. The experimental data indicate that high removal efficiency is obtained at optimized conditions viz. higher pH, lower metal ion concentrations, moderate higher temperatures and higher dosage of biosorbents. The biosorption efficiency is recorded 88.98% at pH 6, 48.99% at contact time 70 minutes and 40.01 % at a higher dosage of biosorbent. The regression value is indicating that the order for all used isotherms model is Langmuir> Freundlich > Temkin.

“…The column capacity, q total (mg), for a given set of conditions in the column was calculated from the area under the plot of adsorbed Cr(VI) concentration, C ads (mg/L), vs. time multiplied by flow rate, F (mL/min) [26]. The equation for the calculation of maximum packed bed column capacity is represented as follows:…”

A B S T R A C TThe removal of Cr(VI) from aqueous solution by a novel Swietenia Mahogani fruit shell physically activated carbon (SMFS-PAC) was examined in a packed bed column study. The effects of significant parameters such as feed flow rate, bed depth, and initial Cr(VI) concentration were studied. Column data obtained at different conditions were described using the Thomas, Bed depth service time (BDST), Adams-Bohart, and Yoon-Nelson model in order to predict the breakthrough curves and to evaluate the model parameters of the packed bed column studies data. Among the models used, Thomas, BDST, and Yoon-Nelson model, respectively, fitted to the experimental data very well. The SMFS-PAC column study states the value of the good adsorption capacity for the removal of Cr(VI) from aqueous solution.
