Studies on the Agrowaste in Phytoremediation by Treating Textile Dye
V. Ramya [3] | S. Karpagam [7]
Abstract: Phytoremediation is a green technology that shows one of the ways to solve the problem of heavy metal pollution, and which shows many encouraging results. The plant used for remedy van hyper accumulate toxic heavy metals in their tissues, convert the pollutants to less toxic compounds and volatilize them [sweta et al., 2017]. In this present study, Paddy husk, corn cob shreds, coconut coir, sugarcane bagasse and wood powder were selected as an inexpensive adsorbent in the elimination of heavy metals from the textile dye. The absorption of heavy metals was estimated by AAS. The present study is focused to find the potential of various natural carriers for the treatment of textile dye. The Agro-wastes namely paddy husk, corncob shred, coconut coir, sugarcane baggase and wood powder are a natural coagulant which shows biosorption and phytoremediation activity. In this research, an attempt has been made to analyse the biosorption of heavy metals by Agrowastes namely paddy husk, corncob shred, coconut coir, sugarcane baggase and wood powder from the textile dyes. Heavy metals were estimated by atomic absorption spectrophotometer. The toxicity level of the treated dye was analysed by green gram germination with pot study bioassay and phytoremediation. Shoot length and root length of the germinated seeds were measured and seedling vigour index were calculated. The heavy metal removal efficiency of the agrowaste namely paddy husk and corn cob shred was higher there by making both the agrowastes a promising absorption for industrial textile treatment. These agro based compound could replace the chemical coagulant and is an environmentally friendly approach to textile dye treatment.
