Dataset and kinetic model reaction compilation for the radical-induced degradation of formic acid and formate in aqueous solution

摘要

This article contains the individual datasets and complete reaction kinetics compilation for the formic acid/formate component of the kinetic model described in “Radiolytic Degradation of Formic Acid and Formate in Aqueous Solution: Modeling the Final Stages of Organic Mineralization under Advanced Oxidation Process Conditions” . Gamma irradiation data were collected for aqueous sodium formate solutions under pH?=?1.5 and 9.0 conditions. To determine the optimum conditions necessary to effectively mineralize formic acid/formate in an Advanced Oxidation Process utilized for water treatment, several solution compositions were evaluated: air, nitrogen, and nitrous oxide saturation. Data were collected by a combination of high performance liquid chromatography and gas chromatography. These measured values were used to construct a kinetic computer model, by combining with published literature rate coefficients and optimizing specific important rate coefficients to afford the best agreement with experimental data.
