Calix[4]arene Resin, An Efficient Adsorbent for Azo Dyes

ABSTRACT

Dyes are a potential menace and are considered major contributors to environmental pollution. However, the cleanliness of the environment from colored toxicants is a challenging task of the contemporary era. In this regard, this approach is based on the confiscation of hazardous dyes. The main features of this work are the synthesis and the application of newly synthesized calix[4]arene grafted Amberlite XAD-4 (resin 5) for the selected methyl orange (MO) and methyl red (MR) azo dyes removal from aqueous environment. The adsorption ability of resin 5 for the selected azo dyes was evaluated through optimizing various parameters. Moreover, treatment with real water samples reveal that newly synthesized resin is an extremely effective adsorbent for the removal of the selected azo dyes from aqueous media.
