TL;DR: In this paper, a single-stage batch adsorber was designed for adsorption of brilliant green dye (BG) by guava seeds (AGSC) based on some experimental parameters such as contact time (5-40 min), adsorbent mass (0.01-0.08 g), temperature (25°C-95°C), pH (3-10), and initial dye concentration (10-100 ppm).
Abstract: In this research, brilliant green dye (BG) has been removed from synthetic wastewater using activated carbon derived from guava seeds (AGSC) which was collected as a waste product from factories producing juice concentrates. A single-stage batch adsorber was designed for adsorption of BG by AGSC based on some experimental parameters such as contact time (5–40 min), adsorbent mass (0.01–0.08 g), temperature (25°C–95°C), pH (3–10), and initial dye concentration (10–100 ppm). The maximum adsorption capacity of AGSC was found to be 80.5 mg/g using the Langmuir isotherm model which is the best-fitted model for the process. The experimental data were fitted well with the pseudo-second-order kinetic model. The changes in functional groups, surface morphology, and chemical composition of AGSC before and after adsorption were identified by Fourier transform infrared spectroscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, respectively. The specific surface area of AGSC was measured to be 605.1 m2/g using Brunauer– Emmett–Teller analysis. Pore volume and pore diameter were found to be 0.57 cm3/g and 3.78 nm, respectively. The thermodynamic study proved that adsorption of BG on AGSC was physiosorptive (ΔG = –7.7 kJ/mol) and spontaneous at high temperature (ΔH = 13.4 kJ/mol, ΔS = 0.07 kJ/mol K).

TL;DR: In this article, a nano zeolite photocatalyst with cerium oxide photosensitizer over Zeo-NaX was used for the degradation of green dye with visible light irradiation (100 W tungsten lamp).
Abstract: Synthesis of zeolite NaX (Zeo-NaX) from coal fly ash and its development into a photocatalyst is a rarely studied current research field. The present work focuses on this field by using cerium oxide photosensitizer over Zeo-NaX. The ceria supported zeolite-NaX (CeO2/Zeo-NaX) was prepared by introducing nanosize CeO2 into Zeo-NaX framework through ion-exchange method. The prepared catalysts were characterized by FT-IR, XRD, SEM, EDX, BET Surface area, and DRS techniques. Photocatalytic degradation of brilliant green dye (BG; 10 ppm) over the synthesized photocatalyst was studied with visible light irradiation (100 W tungsten lamp). The effects of pH, dye concentration, and catalyst dosage were also studied on the degradation reaction of BG. By varying the pH, dye concentration, and catalyst dosage of the observed percentage of photocatalytic degradation of BG are (28-100 %), (80-94 %) and (77-94 %) respectively. Thus the present work established the development of nano zeolite photocatalyst with CeO2 photosensitizer.
