Biodegradation and Bio decolorization Of Textile Dye Effluent Using Nanoparticle Synthesized from Hibiscus Cannabinus

Abstract

Water contamination is a big global problem and some heavy metals in water have caused serious damage
to the health of animals and human beings, it is considered to be one of the most serious environmental
pollutants. Textile Industries are the largest social and economic perspective in India that discharges
tremendous amounts of dye stuff into the water containing recalcitrant compounds, pigments and dye etc.
Azo dyes represent the largest production volume of dye chemistry today and their relative importance may
even increase in the future. Azo dyes are the most important synthetic colorants which have been widely
used in printing, paper manufacturing, etc. The aim of this study is to identify the textile dye degrading
efficiency and evaluation of their heavy metals resistant pattern from nanoparticles synthesized Hibiscus
cannabinus. The dye effluent samples were collected from in and around Tiruppur, Tamilnadu, South India.
The decolorization efficiency of dye was measured using UV-Vis spectrophotometer and the maximum
efficiency 92% was obtained on 7th day. The ability of the prepared SNPs for degrading heavy metals ions
(Pb2+
, Cu2+
, Cd2+
, Cr3+
, Hg2+ and Ni2+) from textile dyes was studied and measured using Atomic
Absorption Spectrophotometer (AAS). The maximum degrading efficiency of Pb2+, Cu2+, Cd2+, Cr3+, Hg2+
and Ni2+ were found to be 85.71, 84.56, 90.26, 84.61, 81.81 and 91.42% was obtained on 7th day
respectively. Nanoremediation is one of most effective ways to degrade dye stuffs and some heavy metal
ions.
