Adsorption Characteristics and Behaviors of Natural Red Clay for Removal of BY28 from Aqueous Solutions

The present study deals with the analysis and adsorption of Basic Yellow 28 BY28 onto low cost natural red clay NRC . Adsorbent characterized by XRD, SEM, TG DTA, BET and BJH. The effect of the contact time, the temperature, the initial concentration, the pH and the adsorbent mass and on adsorption process were investigated using by batch adsorption technique and then the adsorption isotherm, kinetics, thermodynamics and equilibrium studies were performed. The pH effect on the removal of BY28 efficiency was not important. It was found that the isotherm model best suited to the equilibrium data obtained from the adsorption of BY28 on NRC was the pseudo second order. It was found that the kinetic model best suited to the data obtained from the adsorption of BY28 on NRC was the Langmuir model. The maximum monolayer adsorption capacity was 370 mg. g 1. In the thermodynamic studies, it can be said that the adsorption of BY28 onto NRC takes place spontaneously, physically and endothermic ally. Finally, the use of NRC shows a greater potential for the removal of cationic dyes, as no costly equipment is required.

Removal of Tar-Chrome Red-B dye by Adsorption onto Natural Diatomite

In this study; the textile industry from using chromium dyes was removed from wastewater by low- cost diatomite in batch. In batch system, same particle size of diatomite (230-mesh size and surface area 49.0408 m2 /g) and kept at pH 5.10 and five different amounts of sorbent were used. The effect of the temperature on adsorption was evaluated with using three different temperatures. As result of the experiment, 81.072% of the chrom dyes was removed from the wastewater in conditions of using 230 mesh sieve, at 30 oC temperature for 8h in batch system but chrom dyes was removal for different min in batch system,61.992 %, 61.502 %, 63.926 %, 61.174 % and 61.895 % (15min, 30min, 60min, 180min and 300) respectively. Also, the equilibrium adsorption isotherms have been analyzed by Langmuir and Freundlich models.The adsorption values were fitted langmuir and Freundlich adsorption models. Langmuir adsorption capacity were found to be 25.04, 20.08 and 14.68mg/g at 25, 30 and 35 oC respectively. In addition, the filtrates were subjected to a comprehensive colorimetric appraisal using the CIE L∗ a ∗ b ∗ colour space system.

Removal of fluoride from water by NiAl layered double hydroxide prepared by solvothermal method

NiAl layered hydrotalcite was prepared by solvothermal method and the adsorption performance of F - in water was studied. According to the experimental results of single factors, heat treatment can increase the adsorption performance of the samples, but the higher roasting temperature can cause hydrotalcite layered structure destroyed, in this study, optimal calcination temperature is 150℃. As-prepared absorbent was calcinated at 150℃, various conditions such as initial fluorine ion concentration, adsorbent dosage, solution pH value, interfering ion survived together, adsorption temperature and adsorption time etc, were investigated. The sample was characterised by XRD and TEM, and the adsorption kinetics and adsorption isotherms were also analyzed. The adsorption equilibrium was achieved within 24 h on the adsorption reaction of fluoride ion in water. Adsorption isotherms fitted the Freundlich model. The adsorption kinetic fitted well the second-order dynamics model.
