Photoassisted degradation of rhodamine B using poly(ε‐caprolactone) based nanocomposites: Mechanistic and kinetic features

Abstract

The efficiency of poly (ε‐caprolactone)‐cloisite 10A nanocomposite membrane in removing/degrading of an amphoteric dye (rhodamine B) from aqueous samples under visible light is investigated in detail. Nanocomposite membranes were prepared by electrospinning technique using acetone‐chloroform mixture as solvent. The synthesized nanocomposites were used to degrade rhodamine B from aqueous samples under visible light conditions using a 50 W light‐emitting diode lamb. Samples were withdrawn at definite intervals of 30 min and analyzed using UV–vis spectroscopy, LC‐Q‐ToF/MS‐MS, and antibacterial studies. Detailed chemistry of the rhodamine B degradation is reported by interpreting experimental results and using first‐principles density functional theory calculations. Cytotoxicity tests confirm the eco‐friendly nature of end product obtained. Nanocomposite with 9 wt% of cloisite 10A, effectively converts rhodamine B to eco‐friendly products within almost 3 h. To the best of our knowledge, no work has been reported on the use of poly(ε‐caprolactone)‐cloisite 10A nanocomposites for dye removal from water samples.

“…Rhodamine B is an organic dye widely used in textile industry as a dyeing agent. Owing to the high stability of the dye, it remains as a water pollutant [12]. Being a carcinogenic material posing adverse effect to ecosystem, the possibility of effective removal of Rhodamine B using synthesized MoO 3 is studied .Evaluation of the photocatalytic activity of synthesized MoO 3 for removal of Rhodamine B in aqueous medium was studied.…”

Mesoporous degradable chitosan-based monoliths: synthesis and applications toward water purification

“…5 Therefore, developing cost-effective materials and techniques for the sequestration of toxic contaminants from water has gained significant research priority in recent years. 6 Several strategies were developed and reported in the recent past to purify water, such as adsorption, 7,8 photodegradation, 9,10 electrochemical oxidation, 1 etc. Among these, adsorption has been regarded as one of the simplest, most efficient, and cost-effective ways for the separation of trace contaminants from water.…”
