In present generation removal of chromium ions plays very important role for performing charcoal. Chromium ions are removed from polluted solutions which are coming from Lagenaria siceraria plant stems. By using XRD, FTIR and SEM- EDAX will perform the analysis of absorbed substances in surface chemistry. To increase the initial concentration adsorption is utilized. While performing adsorption process removal of contact time process is also involved. Lesser elongation, ionic strength is obtained for pH dependent based on metal ion. Second order of structure model is followed continuously in the structure of data. Suggestions are given in thermo dynamics like activation enthalpy, activation entrophy, activation Gibbs free energy, and activation energy, has been from an idea and possible of mechanism.
