Structural modification of regenerated fuller earth and its application in the adsorption of anionic and cationic dyes

Fuller's earth is an inorganic material used in the electric industry for dielectric oil regeneration. After decontamination treatment, Fuller's earth is regenerated and reused. In this study, the removal capacity of regenerated Fuller for the treatment of water contaminated with dyes of d...
