چکیده    background: in the present study, the photocatalytic (tio2/uv) batch process has been used for the methyl orange (mo) degradation.methods: in the catalyst range from 0.25 to 1.5 g/l, the optimum concentration of tio2 was found to be 0.5 g/l. the kinetic behavior of mo degradation has been evaluated using the nonlinear form of pseudo-first order and pseudo-second order models.results: the goodness of the fit was evaluated using the correlation coefficient r2 value and the mean square error (mse) function.conclusion: the kinetic studies revealed that the pseudofirst order model (k1 = -0.0593 min^-1) is more suitable to fit the experimental data (r2 = 0.957, mse = 0.00271) of mo degradation.
