Efficient degradation of dyes by enhanced chitosan nanocarriers loaded 1000C Boneset

Abstract

Around 105 tons of synthetic dyes are produced every day. Each year, textile waste effluents release non‐biodegradable textile dyes into natural streams and underwater bodies. Due to harmless and less time‐consuming properties, nanoparticle synthesis from plants has recently been experimented with. These herbs belong to a big genus of tropical composite herbs with heads of white or purple flowers primarily found in the tropics. They have several medical applications. In this study for different concentrations of chitosan, Boneset 1000C is formulated. Nanocarrier boneset 1000C loaded using ionotropic gelation method were used. Boneset 1000C with different concentrations (0.5%, 1%, 1.5%, and 2%) for both molecular weight chitosan nanocarriers obtained 33% for low molecular (LM) and 99% for high molecular (HM) encapsulation efficiency. Nanocarriers were characterized by UV–Vis spectrophotometer at 365 nm, FTIR, antioxidant assay, and scanning electron microscope. Mean particle size of 1000C formed by 0.5% HM and 1.5% LM were found to be spherical in shape with sizes 73.79 and 75.08 nm, respectively. Antioxidant assay resulted in inhibitory values of 84.42 and 34.36 mg for the test sample and quercetin respectively. The performance of chitosan with and without nanoparticles for dye degradation showed a 33% reduction in commercial dyes.
