The aerial oxidation of hydroquinone in a freshly prepared developer solution at 20°C has been studied through the measurement of concentration changes by a spectrophotometric method. The concentration of consumed hydroquinone is directly proportional to time, and the equation tIl2 = C, / 0.0786 was obtained to calculate the half-life of the developer. In this equation, the half-life is in ...

The oxidative modification of low density lipoprotein (LDL) may play an important role in atherogenesis. Antioxidants that can prevent LDL oxidation may act as antiatherogens. Our understanding of the mechanism of LDL oxidation and factors that determine its susceptibility to oxidation is still incomplete. Copper is a candidate for oxidizing LDL in atherosclerotic lesions. The binding of copper...

The oxidation reactions of BaLaCuS3 in the artificial air atmosphere were studied at different heating rates temperature range 50–1200 °C. stages determined by DSC-TG, XRD and IR–vis methods. kinetic characteristics proceeding obtained with use Kissinger model a linearized form. Compound was stable up to 280 Upon further 1200 °C, this complex sulfide underwent three main stages. first stage is ...
