Porous titania was successfully synthesized by an ultrasound-assisted sol-gel route. The synthesis process was empirically modeled and optimized using the response surface methodology (RSM). Input variables adopted for optimization dealt with the weight ratio of precursors ( r ) and the sonication time ( t ), representing the used factors in the synthesis procedure. With regard to application, the synthesized TiO 2 samples were tested for the photodegradation of two water-soluble organic pollutants under UV-Vis irradiation. Optimal conditions for the efficient pollutants' photodegradation were found to involve a precursors ratio of 3 and a sonication time of 60 min. Thus, the M5 sample prepared under the founded optimal conditions yielded the maximal removal efficiencies of 98.4% and 46.3% for the photodegradation of CR dye and 2,4-D herbicide, respectively. In addition, the photodegradation kinetics revealed the pseudo first-order rate constants, showing the photodegradation of CR ( k 1  = 8.86 × 10 -2 min -1 ) by M5 sample is about 1.3-fold faster than the photodegradation of 2,4-D pesticide ( k 2  = 6.84 × 10 -2 min -1 ).
