“…On the other hand, during the desorption process, NaOH reacts with calcium-alginate beads and it was completely dissolved due the replacement of calcium and sodium ions. Overall, HNO 3 and HCl was found to have higher resorption efficiencies and similar work has been reported previously [29,30]. The overall MEA adsorbent was found to be cost-effective and feasible for treatment of industrial wastewater treatment.…”

“…For batch desorption experiments, deionized water and 0.1 M of analytical-grade NH 4 Cl, EDTA, CH 3 COOH, HCl, HNO 3 and NaOH were used. In this study, a series of 250 ml of Erlenmeyer flasks containing 100 mL of desorption solution was mixed with 10 g of dye-loaded MEA at room temperature.…”

“…Further, the use of NH 4 Cl was resorbed by only \20 %, whereas CH 3-COOH and EDTA give 50-60 % of the desorption efficiency. The use of acids such as HNO 3 and HCl gives more than 90 % de-resorption efficiency which can be attributed to the fact that the AB-FFS dyes react faster with acids than bases. On the other hand, during the desorption process, NaOH reacts with calcium-alginate beads and it was completely dissolved due the replacement of calcium and sodium ions.…”

In this study, Moringa oleifera-encapsulated alginate beads (MEA) were synthesized using Ca-alginate for the removal of anionic blue-FFS (AB-FFS) dye from an aqueous solution. The synthesized beads were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and BrunauerEmmett-Teller (BET) methods. The influences of initial pH, initial dye concentration and temperature were established in batch mode. The equilibrium biosorption obeyed both the Langmuir and Freundlich isotherm models with Q max of MEA of about 76.92 mg/g at 343 K. Based on thermodynamic data, it was found that the biosorption process was endothermic and spontaneous. Fixed bed column studies were conducted using different parameters such as flow rate and bed height of the biosorbent. The data obtained were fitted with well-established models, namely Thomas and Yoon-Nelson. Desorption of beads could be achieved by a minimum of five successive cycles without significant loss of initial dye concentration in the batch mode. Experimental results indicate that MEA appears to be a promising biosorbent material used for treating the textile wastewater.

“…This is mainly due to the well-developed porous internal structure of activated carbon and its various surface functional groups, and hence its remarkable adsorption properties. In this regard, activated carbon has been evaluated extensively for the treatment of aqueous effluents containing different classes of dyes [3,[6][7][8].…”

Activated carbons prepared from two bituminous coals were used to adsorb phenol in aqueous solutions. The major diþ erence between the coal precursors is the oxygen content. The carbon preparation consisted of carbonization of the coals followed by activation in to various CO 2 extents of burn-oþ . Experimental results show that the amount of phenol adsorbed generally increases with the BET surface area of the carbon. The carbons prepared from the coal with a higher oxygen content have larger surface areas, and, therefore, exhibit higher capacities for phenol. The surface area of the carbon increases with the extent of carbon burn-oþ , whereas the increase in the adsorptive capacity due to the increasing burn-oþ level does not show a linear relationship with the increase in area ; the ratio of the capacity to BET surface area is not constant and decreases with the burn-oþ level. This has been attributed to the accessibility of phenol to the surface being aþ ected by the length of diþ usion path, which is an increasing function of the burn-oþ level or the particle size. The amount of phenol adsorbed decreases with the temperature for these carbons. It was found, according to the Langmuir model, that the adsorption process was signiücantly aþ ected by the oxygen content in the coal precursors.1999 Society of Chemical Industry (
