Investigation of Dye Removal Capability of Blast Furnace Slag in Wastewater Treatment

Blast Furnace Slag (BFS) is a by-product of the iron ore processing industry with potential to be used in different industrial applications. In this research, BFS was examine its ability for dye removal from wastewater. The efficiency two types samples cationic methylene blue (MB) and acidic methyl orange (MO) dyes investigated results found that optimal conditions treatment wastewater were 80 g/L adsorbent dose 1 h time both dyes. more effective MO than MB dye. Under shorter residence times, showed reverse trends removing higher concentrations MO. chemistry had additional impacts on removal. Higher basicity lower adsorption when applied at smaller concentrations, while concentrations. has role pre-treatment contaminated may contribute reduced use expensive adsorbents, such as activated carbons.
