The separation of toxic pollutants such as Pb2+, Cd2+, and Al3+ from water is a constant challenge as contamination of natural water bodies is increasing. Al3+ and especially Pb2+ and Cd2+ are ecotoxic and highly toxic for humans, even in ppb concentrations, and therefore removal below a dangerous level is demanding.

Abstract:

By means of solution polymerization, a series of cross-linked starch-g-polyacrylamide/ montmorillonite (St-g-PAM/MMT) nanocomposites were prepared and used to adsorb methylene blue (MB). The effects of different preparation conditions on the adsorption capacity of the nanocomposites were investigated. The experimental results demonstrated that the prepared St-g-PAM/MMT nanocomposites were effective adsorbents for removal of MB from aqueous solution. Furthermore, adsorption capacity increased with the MMT contents up to 14% and decreased as the MMT contents further increased. Adsorption capacit

Abstract:

A type of cross-linking starch microsphere (CSMs) has been synthesized via reversed phase suspension method. Crosslinked starch microsphere has good adsorption performance to metal ions in water. The adsorption kinetics of Co (II) on the CSMs, selectivity of adsorption CSMs towards Co (II),Cu (II),Pb (II),Cd (II) and adsorption effects of media towards Co (II) were investigated. The CSMs and its adsorption product were comparatively characterized by X-ray diffraction (XRD). The results showed that The adsorption rate is mainly controlled by liquid film diffusion, and the constant of adsorption

Abstract:

The recovery of a cationic dye, methylene blue (MB), from the residue generated during its removal via adsorption on starch-based adsorbents from aqueous solution was studied. Adsorption characteristics of MB on wheat flour (WF) and pure starch were analyzed using UV-visible spectroscopy. WF and starch were loaded with an optimum amount of MB producing MB-WF and MB-starch, respectively, leaving residues. The desorption characteristics and % recovery of MB from both the synthetic wastes were determined. The effects of yeast and temperature on the recovery of MB were also investigated. The mecha

Abstract:

ABSTRACT The Lactobacillus amylovorus alpha-amylase starch binding domain (SBD) is a functional domain responsible for binding to insoluble starch. Structurally, this domain is dissimilar from other reported SBDs because it is composed of five identical tandem modules of 91 amino acids each. To understand adsorption phenomena specific to this SBD, the importance of their modular arrangement in relationship to binding ability was investigated. Peptides corresponding to one, two, three, four, or five modules were expressed as His-tagged proteins. Protein binding assays showed an increased capaci

Abstract:

The crosslinked starch microspheres(CSM) were synthesized from soluble starch by inverse suspension polymerization with N,N′-methylenebisacrylamide as cross-linking agent. Experiments showed that adsorption isotherms of CSM for Cd(II) and Pb(II) could be described by Freundlich model, while that for Cu(II), Cr(III) fits well with Langmuir equation. The equilibrium capacity of Cu(II), Cr(III), Cd(II) and Pb(II) on the CSM were 1.10, 0.87, 0.35 and 0.31 mmol•g-1 respectively at 25°C, when adsorption process was undertaken with initial concentration from 0.7 to 11.5 mmol•L-1, and adsorption kinet

Abstract:

A new chelating material dialdehyde m-phenylenediamine starch (DASMPA) was synthesized by reacting m-phenylenediamine with dialdehyde starch. The obtained material was characterized by element analysis and Fourier transform infrared (FT-IR) spectra. The FT-IR of DASMPA showed an absorption peak at 1605.95 cm−1 indicating the formation of a Schiff base (C=N). Adsorption activity of DASMPA for Zn2+ was also investigated in terms of contact time, pH, the initial Zn(II) concentration and temperature, the results revealed that pH = 5, t = 1 h were the optimal conditions.

Abstract:

Chromium is extremely toxic and considered a priority pollutant. It is compulsory to control the discharge of chromium compounds into aquatic systems in order to prevent severe environmental problems. Among all the treatment methods, adsorption has been proved to be a substantial method for the removal of chromium from wastewater. Recently, a variety of starch-based materials have been used as chromium adsorbents. The present review provides the recent development in the sorption capacities of starch-based sorbents for chromium, new starch-based materials and their advantages for the removal o
