In a quartz cell, a methanol solution of methylcobalamin, arsenic (inorganic trivalent arsenic) and trimethylsulfoxoniuim bromide (TMSBr) was prepared. The total volume of the solution was 0.5 mL, the concentration of methylcobalamin was 148 μmol/L, the concentration of arsenic was 6.5 mmol/L, and the concentration of TMSBr was 532 mmol/L. Further, 50 mg of titanium oxide was mixed thereto. The quartz cell was irradiated with an ultraviolet ray for 24 hours using a high-pressure mercury lamp (365 nm of central wavelength, 5 mW/cm2). A qualitative analysis was performed on a yielded product every 2 hours using a HPLC-ICP-MS, and the number of catalyst cycle was determined. The result is shown in FIG. 1.
