"The reaction of peroxomonosulfate (PMS) with glycolic acid (GLYCA), an alpha hydroxy acid, in the presence of Ni(II) ions and formaldehyde was studied in the pH range 4.05-5.89 and at 31 degrees C and 38 degrees C. When formaldehyde and Ni(II) ions concentrations are similar to 5.0 x 10(-4) M to 10.0 X 10(-4) M, the reaction is second order in PMS concentration. The rate is catalyzed by formaldehyde, and the observed rate equation is (-d[PMS])/dt = (k(2)'[HCHO][Ni(II)][PMS](2))/{[H+](1 + K-2]GLYCA])}," scientists in Madurai, India report.
"The number of PMS decomposed for each mole of formaldehyde (turnover number) is 5-10, and the major reaction product is ...
