Citric acid-cross linked with magnetic metal-organic framework composite sponge for superior adsorption of indigo carmine blue dye from aqueous solutions: Characterization and adsorption optimization via Box–Behnken design

The Application of Chitosan-Based Adsorbents for the Removal of Hazardous Pollutants from Aqueous Solutions—A Review

“…For example, phenolic-grafted chitosan can be prepared using three different methods: free radical initiation, carbodiimide coupling, and enzyme catalysis [39]. However, it can be observed that whenever possible, attempts are made to develop the simplest methods possible, e.g., those in which the necessary ingredients are mixed under specific conditions (e.g., at elevated temperatures or under microwave-assisted heating) [28,29,[40][41][42].…”

The efficiency of Raphia hookeri adsorbent in indigo carmine dye removal: Economy depth via chemometrics

“…Dye contamination can disrupt aquatic food chains by hurting or killing primary producers, which in turn influence higher trophic levels. Some dyes can bioaccumulate in aquatic organisms, resulting in larger concentrations among predator species [ 5 ]. Indigo Carmine (ICD) belong to a class of water-soluble semi-synthetic dye.…”

“…Indigo Carmine (ICD) belong to a class of water-soluble semi-synthetic dye. ICD has been used for various industrial applications including the food (such as desserts, beverages and candies), textile, cosmetics, pharmaceuticals and plastic industries [ 4 , 5 ]. ICD is a threat to aquatic life, and the byproducts of its degradation are known to be mutagenic, carcinogenic, allergenic, and highly toxic, resulting in a variety of health issues [ 8 ].…”
