development of an intensified immobilized static mixer reactor for photocatalytic degradation of ibuprofen: statistical modelling and optimization

A static mixer reactor was designed and fabricated to overcome the external and internal mass transfer limitations which restrict photocatalytic degradation process performance# in this regard, the application of the static mixed reactor was evaluated for degradation of ibuprofen while rgo/ag3po4 as an efficient visible-light-driven photocatalyst was immobilized on the external surface of the reactor blades# the effect of operational parameters including the initial concentration of ibuprofen, irradiation time, ph, and photocatalyst dosage on the photocatalytic degradation efficiency was studied and then optimized through the desirability function technique# results indicated that the designed static mixer photocatalytic reactor had high efficiency (92#49%) for degradation of ibuprofen under optimized conditions, set as 20 mg/l of the initial concentration of ibuprofen, 5 of ph and 90 min of irradiation time#
