TL;DR: In this article, Mn(II)-incorporated MCM41 is used as catalyst for oxidation of 2-chlorophenol (2-CP), 2,4-dichlorophenol(2-DCP), and 2, 4-6-trichlor-phenol (3-TCP) in water with or without an oxidant (H 2 O 2 ).

TL;DR: A suite of analytical methods for determining the amount of organic sulfur (carbon-bonded sulfur and ester sulfate) and inorganic sulfur (sulfate and sulfide) is described in this paper.
Abstract: A suite of analytical methods for determining the amount of organic sulfur (carbon-bonded sulfur and ester sulfate) and inorganic sulfur (sulfate and sulfide) is described. Organic sulfur fractions, which have often been ignored, are major constituents of oxic substrates and have a major role in sulfur dynamics. Methods of sample preparation and a modification of the Johnson-Nishita digestion-distillation apparatus are given. HCl digestion, Zn-HCl reduction, hydriodic acid reduction, sulfate extraction, wet oxidation and dry oxidation are utilized for determining sulfur constituents. With only minor modifications these analyses were adapted for examining 35S transformation rates. Results from these analyses on sewage sludge, lake sediment, soil, and water demonstrate the usefulness of these methods.

TL;DR: In this paper, the authors studied the kinetics of wet air oxidation of oxalic acid and formic acid in the presence and absence of a cupric sulfate catalyst in the temperature range of 120-245 C and oxygen partial pressure of 0.345-1.380 MPa.
Abstract: Oxidation of lower molecular weight monobasic and dibasic acids such as formic acid, acetic acid, glyoxalic acid, and oxalic acid is often the rate-controlling step during wet air oxidation (WAO) of an aqueous waste stream exhibiting very high chemical oxygen demand (COD). The kinetics of WAO of glyoxalic acid and oxalic acid was studied in absence and presence of a cupric sulfate catalyst in the temperature range of 120--245 C and oxygen partial pressure of 0.345--1.380 MPa. The wet oxidation of oxalic acid was found to require more severe conditions as compared to glyoxalic acid. The reaction mechanism and kinetic model have been discussed.
