Adsorption of methyl orange by porous membranes prepared from deep eutectic supramolecular polymer-modified chitosan

Anionic dye removal by immobilized bacteria into alginate-polyvinyl alcohol-bentonite matrix

“…The statistical analysis employed Analysis of Variance (ANOVA) to investigate the significant different between each treatment on beads immobilization and free cell, which expressed as mean of three replicates ± SD (standard deviation). The difference between mean values at confidence level of 5% (P < 0.05) were considered as statistically significant between group mean [ 1 , 38 ].…”

“…Dyes are materials with several functions and are often used in the textile industry for coloring fabrics and textiles. Various types of dyes have been identified [ 1 ], one of which is classified based on charge, depending on the chemical structure. For example, anionic dyes have a negative charge when dissolved in water, including methyl orange (MO), which is usually used for dyeing textiles such as wool, cotton, and silk fabrics [ 2 , 3 ].…”

Methyl Orange Adsorption on Biochar Obtained from Prosopis juliflora Waste: Thermodynamic and Kinetic Study

“…The sulphonic group is responsible for the high MO solubility in water; in addition, the main drawback of MO is the harm to the environment and human beings [11]. Many strategies have been reported to remove MO from the aquatic environment (e.g., biological treatments [12], oxidation [13], membranes [14], adsorption [15], photocatalytic degradation [16], and coagulation-flocculation [17]). However, despite different options, the traditional methods have some disadvantages that include energy requirements, costs, incomplete removal, and harmful by-products [18,19].…”
