Description :
Thousands of dyes have since been prepared and, due to the vastly improved properties imparted upon the dyed materials; organic dyes have replaced the traditional natural dyes. Nano-scale zero valent iron particles provide cost effective solution to many of the environmental problems. The green synthesis of zero valent iron nano particle by using green tea was carried out. Graphene oxide has numerous adsorption abilities being well explored towards water purification. In this study, a novel environmental adsorbent iron nano particle immobilized on graphene oxide was prepared. The effects of various experimental parameters such as contact time, pH and dosage of the adsorbent graphene oxide-iron nano particle composite on methylene blue (MB) removal were investigated. 100mg/100ml was sufficient to remove 95% of dye in 70 minutes from 10ppm dye solution. The equilibrium adsorption data were described by the Langmuir and Freundlich’s adsorption isotherms. The unprecedented adsorption performance may be attributed to both the synthesis methodology and adsorption conditions.
