Multivariable analysis of 2,4-d herbicide photocatalytic degradation

The 2,4-D herbicide degradation of TiO2 suspensions in tap water was evaluated under artificial irradiation conditions. The response surface methodology (RSM) was applied to evaluate the effect of variables such as: catalyst concentration, herbicide concentration, pH, and the volumetric flow on the...
