The present study deals with removal of organic dyes from wastewater onto natural dispersed sorbents, namely bentonite, glauconite and paligorskyte. The obtained data were fitted to various theoretica...
In this paper, Shuwaymiyah palygorskite in the Sultanate of Oman has been characterized mineralogically by X-ray diffraction (XRD) and electron microscopy, chemically by oxide compositions, structural...
The bentonite coated chitosan which was prepared of natural bentonite used as raw material and chitosan used as modifying agent applied in the treatment of livestock wastewater. The optimal preparatio...
The aminated collagen fiber (ACF) was prepared by modifying collagen fiber (CF) with ethylenediamine and cynuric chloride as crosslinking agent. The appropriate modification conditions were optimized ...
Polyacrylonitrile (PAN) and bentonite (B)/zeolite (Z)-PAN composites were prepared by direct polymerization of acrylonitrile (AN) and AN adsorbed onto B and Z. PAN and the composites were subjected to...
A series of starch-g-poly(acrylic acid)/sodium humate (St-g-PAA/SH) hydrogels were prepared and used to adsorb Cu2+ from the aqueous solution. The batch adsorption experiments were carried out by vary...
A series of carboxymethyl cellulose-g-poly (acrylic acid)/attapulgite hydrogel composites were synthesized for the removal of cationic dye methylene blue. Various factors affecting the uptake behavior...
Water vapor adsorption on silica gel was investigated using Tian–Calvet-type microcalorimetry. Differential heat of adsorption data was obtained. The setup of microcalorimetry was used volumetric syst...
New pH-sensitive composite hydrogels were synthesized by free-radical graft copolymerization among sodium alginate (NaAlg), sodium acrylate (NaA), and medical stone (MS). Fourier transform infrared sp...
Response surface methodology was employed to optimize the adsorption parameters of Methylene Blue onto a chitosan-g-poly(acrylic acid)/halloysite hydrogel composite with 50% halloysite content. Such o...
1, 10-phenanthroline and triethylamine modified palygorskites were prepared by microwave irradiation, and characterized with FT-IR technique. The effects of contact time, adsorbent dosage, and pH valu...
The aim of this study was the assessment of reduction of chemical oxygen demand (COD) from micro-polluted water using activated carbon-attapulgite composite adsorbent prepared using activated carbon a...
This study investigated the adsorption of congo red by activated carbon-attapulgite composite adsorbent (ACA) and zeolite-attapulgite composite adsorbent (ZA) from aqueous solution. All of these two a...
Adsorption characteristics of Ni (II) by Palygorskite were investigated using a batch adsorption, and the effects of various experimental parameters were discussed. Results showed that the adsorption ...
The adsorption technique using fly ash composite material has been applied for the removal of Cr(VI) from aqueous samples. Batch experiments have been carried out for the adsorption of Cr(VI) onto fly...
