Removal of Brilliant Green from wastewater using conventional and ultrasonically prepared poly(acrylic acid) hydrogel loaded with kaolin clay: A comparative study.

TL;DR: In this paper, the effect of experimental factors such as pH (2-10), particle size (58-150μm), adsorbent dose (0.3-1.5), contact time (5-1500min), initial dye concentration (20-100mg/L), and temperature (25-65°C) on the adsorption of Brilliant Green (BG) dye was investigated.

TL;DR: In this article, an entirely conceptual and critical review of literature is presented, focusing on the tremendous potential of composite hydrogels to remediate dye-contaminated water, and the main drawbacks and challenges associated with the application of these types of materials are reviewed to understand the research gap and limitations regarding their practical use.

TL;DR: The ultrasound-assisted simultaneous adsorption of brilliant green and malachite green onto Mn-doped Fe3O4 nanoparticle-loaded activated carbon as a novel adsorbent as an investigated and analyzed using first derivative spectrophotometry makes it promising for such adsorptive applications.

TL;DR: This review was organized to offer better insights into various types of functional polymer and clays composite membranes developed for efficient treatment and purification of water/wastewater.

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: Experimental results indicate that the prepared MgO powder can remove more than 98% of both dyes under optimum operational conditions of a dosage of 0.2g, pH 8 and a contact time of 5 min for initial dye concentrations of 50-300 mg/L.

TL;DR: The high negative value of change in Gibbs free energy (DeltaG0) indicates the feasible and spontaneous adsorption of BG on RHA, and Langmuir and R-P isotherms were found to best represent the data for BG advertisersorption onto RHA.

TL;DR: In this article, a unified approach for the selection of different operating and geometric parameters for large scale sonochemical reactors with a special emphasis on heterogeneous systems is presented, where the authors make recommendations for optimum selection of frequency of irradiation and power dissipation rate/irradiation intensity as well as the liquid phase physicochemical properties.
