Photocatalytic degradation of RB by the iron complex/H2O2
system was studied by taking 40.0 mL reaction mixture
containing 1.50 · 10–5 M dye solution, 0.3 mL hydrogen
peroxide, and 2.18 · 10–5 MFeCl3 solution in a 100 mL beaker
for untreated solution and 1.50 · 10–5 M dye, 0.3 mL hydrogen
peroxide and 4.37 · 10–5 M iron complex in a 100.0 mL
beaker for treated solution. The
