“…The MICD process is defined as the combination of MW irradiation with a suitable MW absorbent (which is also used as a catalyst) [77], while the MICO process has a similar concept to that of the MICD process, but with the addition of oxidant(s). In other words, the MICO process is the combination of MW irradiation, MW absorbents (as catalysts), and oxidants.…”

“…Moreover, discharging of textile effluents into water source scan cause harmful effects to human health, due to their toxic nature and high stability in environment (Chuah et al, 2005). Crystal violet is one of the widely used cationic dyes in various industries which can enter and accumulate into living organisms (He et al, 2010). Therefore, it is essential to develop environmental friendly and also low cost process for detecting heavy metals and also dyes in industrial effluents.…”

“…It has been used as antifungal and antimicrobial agents. 4 CV is a mutagen, mitotic poison, 5 and proven potent carcinogen, 6 and is toxic to mammalian cells. Moreover, CV has been classified as a recalcitrant molecule because of its poor biodegradation and because it can last for a long time in a variety of environments.…”

A series of chitosan (Ch)-graphite oxide (GO)-modified polyurethane foam (PUF) materials as adsorbents were synthesized by a foaming technique. The adsorbent was characterized through IR spectroscopy, scanning electron microscopy, and thermogravimetric analysis (TGA). Batch adsorption experiments of the cationic dye crystal violet (CV) were carried out as a function of the Ch-GO content (1.0-8.0 wt %), solution pH (2-10), dye concentration (100-300 mg/L), adsorbent dosage (10-60 mg/mL), and temperature (20-45 C). At a lower pH value, the surface of Ch-GO/PUF acquired positive charge by absorbing H 1 ions; this resulted in a decreasing adsorption of the cationic CV dye because of electrostatic repulsion. As the pH of the aqueous system increased, the numbers of negatively charged sites increased by absorbing OH 2 ions, and a significantly high electrostatic attraction existed between the negatively charged surface of Ch-GO/PUF and the cationic dye (CV) molecules. This led to maximum dye adsorption. The kinetics, thermodynamics, and equilibrium of CV adsorption onto Ch-GO/PUF were investigated. The equilibrium data for CV adsorption fit the Langmuir equation, with a maximum adsorption capacity of 64.935 mg/g. The adsorption kinetics process followed the pseudo-second-order kinetics model. Thermodynamic parameters analysis revealed that the adsorption of CV from an aqueous solution by a Ch-GO modified PUF material was a spontaneous and endothermic process. We concluded that Ch-GO/PUF is a promising adsorbent for the removal of CV from aqueous solutions.
