Variation of pH, conductivity and potential values in chromium (VI) removal by wool was investigated in this study. In addition to chromium (VI) concentrations, pH, conductivity and potential values were also traced during the experimental studies. After applying linear regression to experimental data, it was seen that there was a relationship between pH, conductivity, potential values and chromium (VI) concentrations in the aqueous solution after treatment with wool. This relationship was evaluated in the light of the analyses of the linear regression. Kinetic data and adsorption isotherms for chromium (VI) adsorption by wool were also determined.
