A series of aminated chitosan microspheres were prepared from chitosan,and then an affinity dye-ligand,Cibacron Blue F3GA,was covalently coupled.The maximum attachment of cibacron blue F3GA was 494 μmol/g.Albumin adsorption onto cibacron blue F3GA-attached chitosan microspheres was investigated.The human serum albumin (HSA) equilibrium adsorption capacity was 79.8 mg/g (wet beads).The adsorption equilibrium isotherms appeared to follow a typical Langmuir isotherm.The highest desorption ratio (100%) was achieved by using an eluent of 1.0 mol/L NaSCN (pH 8.0).The cibacron blue F3GA-attached chitosan microspheres could be reused without significant decreases in the adsorption capacities. 展开更多

Adsorption processes have received special attention for contaminants removal thanks to their capability to gen- erate effluents with high quality as well as their simple design. In the current work, the agro-waste residue avo- cado peel is proposed to be used as alternative to conventional activated carbons whose use is sometimes restricted to high costs, upgraded by their exhausting after long term operations. The carbonization procedure was optimized and analyzed through factorial design and response surface methodology by evaluating temper- ature (400-900 ℃) and time (30-90 min) effects: optimal conditions were found at 900℃ and 65 min, gener- ating an adsorbent with 87.52 m2.g 1 of BET surface area, a mesopore volume of 74% and a zero point charge at 8.6. The feasibility of the carbonaceous material was proved for the removal of a variety of dyes by investigating substrate (10-50 mg.L 1) and solid (0.5-20 g.L-1) concentration effects and statistical significance: complete removal of Naphthol Blue Black and Reactive Black 5 was reached under optimal conditions (10 mg.L 1 and 20g.L 1 of dye and solid, respectively), while Basic Blue 41 was eliminated by using 13.4 g. L- 1 of the adsorbent. Overall, dyes removal by adsorption on carbonized avocado peel is presented as a promising technology due to the low cost and easy availability of the precursor, as well as the straightforward generation, the satisfactory char- acteristics and the proved adsorption capacity of the adsorbent. 展开更多

The silk sericin is the main residue in silk production and it is found to be a low cost and efficient bio-sorbent. In this study, sericin was characterized with various techniques including SEM (scanning electron micro- scope), XRD, N2 physisorption, FTIR (Fourier transformed infrared spectroscopy) and XPS (X-ray photoelectron spectroscopy). The nitrogen content of sericin was ca. 8.5 mmol.g-1 according to elemental analysis. Dye adsorption by sericin biosorbent was investigated with the acid yellow (AY), methylene blue (MB) and copper (II) phthalocyanine-3,4'4"4'"-tetrasulfonic acid (CuPc) dyes from water. Sericin displayed large capacity for AY andCuPc adsorption with adsorption capacities of respectively 3.1 and 0.35 mmol.g-1, but it did not adsorbed methyl- ene blue dye. This selectivity is due to the basicity of amide groups in seriein biosorbents. 展开更多

Herein a novel aminopropyl-containing ionic liquid based organosilica(ILOS-NH_2) is prepared, characterized and applied as effective adsorbent for removal of crystal violet(CV) dye from wastewater. The ILOS-NH2 material was synthesized by hydrolysis and co-condensation of 1,3-bis-(3-trimethoxysilylpropyl)-imidazolium chloride(BTMSPIC) under acidic conditions followed by treatment with 3-aminopropyl-trimethoxysilane in toluene under reflux conditions. This material was characterized using scanning electron microscopy(SEM), diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS), thermal gravimetric analysis(TGA) and energy dispersive X-ray analysis(EDAX). The material was effectively used in the removal of crystal violet at ambient temperature and showed high capacity and stability under applied conditions. The efficacy of p H, contact time, adsorbent dose, initial dye concentration, temperature, and isotherm studies and the applicability of pseudo-first, second order and Elovich kinetic models have also been investigated. 展开更多
