Increasing surface and groundwater pollution by ammonium and nitrate makes it necessary to find solutions with minimal environmental impacts. Surface absorption is current method to remove soluble contaminations from aqueous medium. For this purpose, using herbal remedies offers cost-effective and availability and environmentally remediation technique. Using herbal nanoparticles as absorbent due to high specific surface and intense reactivity, results in high absorption efficiency.
In this study investigate nitrate removal using Conocarpus Nanostructure as absorbent in aqueous solution. In order to improve absorption capacity Conocarpus Nanostructure has been modified by a chemical method.
The effect of pH, time and absorption dosage has examined in batch system. The equilibrium time and optimum parameters were determined and the kinetic and isotherm models were checked.
The equilibrium time was determined 90 minutes and the optimum adsorption efficiency occurred in pH=3. The optimum absorbent concentration in nitrate solution was determined 0.6 mg/l. the Coefficients and constants related to the kinetic and isotherm models were find. The kinetic and isotherm models evaluation shows that the Ho et. al. and Froundlich models offer the best description.
