“…The batch was made using a photochemical reactor, a magnetic stirrer, a 600 mL vessel and a peristaltic pump to recirculate the solution at a flow of approximately 207 mL min -1 . This system was based on works by da Silva et al 19 and Guimarães et al 20 The bench photochemical reactor consisted of a 42.5 cm long and 4 cm internal diameter borosilicate glass cylinder with a low pressure mercury vapor lamp inserted in the center (15 W, l max of 254 nm, 2.5 cm internal diameter, brand Ecolume). The lamp was in direct contact with the circulating solution.…”
