What is Modified Bituminous Coal for Dye Removal about?

1) The document examines the modification of natural bituminous coal through nitric acid treatment, zinc oxide nanoparticle coating, and conversion to porous graphite to improve its ability to remove safranin-T dye from aqueous solutions. 2) Testing showed that porous graphite had the highest dye removal efficiency of 96% while untreated coal had 62% removal. Adsorption kinetics followed a pseudo-second-order model. 3) The maximum adsorption capacities calculated from the Langmuir isotherm model increase
