Bed depth service time and legit methodologies are very effective in examining ion exchange process for removing boron by columnar operation. They are exployed in this paper for the development of a convenient mathematical model. Such a model provides opportunity for the assessment in process parameters among which are the bed depth, ion exchange rate, influent concentration as well as the pH effect on the service time. Experimentally obtained data in the laboratory fit Bohart-Adams equation on double logarithmic paper as a result of which a linear regression line emerges. This method helps engineers in designing ion exchange columns by means of similar operations.
