Research Abstract |
Recently, the pollution of the soil by heavy metal ions from the industrial effluents is a major threat. Remidial measures were taken by adopting various extraction processes such as the diffusion prevention, the elution prevention, the extraction and the removal process, the decomposition and the decontamination process. It is realized that electro kinetic process is more effective. In this process, the ionized heavy metal ions in the contaminated soil move towards the cathode electrode by the electroendosmose process. The major problem is that heavy metal ion has to be recovered from the water and discharged. Otherwise, it causes secondary pollution. It is realized that the natural zeolite, which is available in abundance, could mitigate the problem of secondary pollution. In the present study, it is realized that by using the zeolite as a cathode material, the heavy metal ion content could be absorbed by the zeolite material. In the present work, a detailed experimental study was formulated to understand the metal ion absorption characteristics of the natural zeolite material.
