TL;DR: It was observed that the rate of dye adsorption follows pseudo-second-order model for the dye concentration range studied in the present case and the estimated values of DeltaH0 and DeltaS0 both show the negative sign, which indicate that the Adsorption process is exothermic and the dye molecules are organized on the kaolin surface in less randomly fashion than in solution.

TL;DR: In this article, the effect of initial dye concentration, contact time, adsorbent dose, stirring speed, pH, salt concentration and temperature were studied in batch mode using commercially available kaolin to adsorb two different toxic cationic dyes namely crystal violet and brilliant green from aqueous medium.

TL;DR: In this paper, the performance and modeling of the separation of oil-in-water (o/w) emulsions using low cost ceramic membrane that was prepared from inorganic precursors such as kaolin, quartz, feldspar, sodium carbonate, boric acid and sodium metasilicate was addressed.
Abstract: This work addresses the performance and modeling of the separation of oil-in-water (o/w) emulsions using low cost ceramic membrane that was prepared from inorganic precursors such as kaolin, quartz, feldspar, sodium carbonate, boric acid and sodium metasilicate. Synthetic o/w emulsions constituting 125 and 250 mg/L oil concentrations were subjected to microfiltration (MF) using this membrane in batch mode of operation with varying trans-membrane pressure differentials (ΔP) ranging from 68.95 to 275.8 kPa. The membrane exhibited 98.8% oil rejection efficiency and 5.36 × 10−6 m3/m2 s permeate flux after 60 min of experimental run at 68.95 kPa trans-membrane pressure and 250 mg/L initial oil concentration. These experimental investigations confirmed the applicability of the prepared membrane in the treatment of o/w emulsions to yield permeate streams that can meet stricter environmental legislations (

TL;DR: In this paper, the use of agricultural solid wastes to remove two classes of dye, cationic and anionic dyes, was discussed and a simple comparison among cationi-and anionic dye adsorption by the same adsorbent was made, thus possibly opening the door for a better understanding of the dye-classified adaption process.
