Activated Periodates and Sodium Percarbonate in Advanced Oxidation Processes of Organic Pollutants in Aqueous Media: A Review

The methods of periodates and sodium percarbonate activation are considered for planning strategic approaches to increasing the efficiency and intensity of oxidative degradation of organic pollutants in aquatic environments. A classification of periodate activation methods is proposed, including activation methods by external energy effects, catalytic activation methods, and other activation methods (e.g., by hydrogen peroxide, by hydroxylamine, activation in alkaline medium). Activation methods for sodium percarbonate were divided into homogeneous and heterogeneous activation methods.

Activation of polyethylene granules by finely dispersed zinc

The results of experimental researches of features of mechanical activation of polyethylene granules with finely dispersed zinc in a ball mill, and also results of research of chemical copper plating of activated polyethylene granules are given. The influence of the ratio of polyethylene granules and fine zinc, the speed of rotation of the ball mill and the duration of activation, as well as the degree of loading of the components in the activation process of polyethylene granules was studied.

INVESTIGATION OF ACTIVATION OF NATURAL CLINOPTYLOLITE BY HIGH-FREQUENCY ELECTROMAGNETIC RADIATION

Natural clinoptilolite is used in a variety of technological processes, in particular as sorbents. In order to achieve high technological and techno-economic indicators of the processes in which zeolite is used, it is necessary to provide them with the highest possible sorption ability. This is achieved by activating natural zeolites by physical, physico-chemical and chemical methods. One of the promising methods of activating natural zeolites is their treatment in the field of ultrahigh-frequency electromagnetic radiation.

Дослідження ефективності активації порошкоподібного полівінілхлориду

Наведено результати експериментальних досліджень особливостей механічної активації порошкоподібного суспензійного полівінілхлориду цинком. Розроблено методику дослідження ефективності механічної активації порошкоподібної полімерної сировини дрібнодисперсними металами. Досліджено вплив співвідношення порошкоподібного полівінілхлориду і дрібнодисперсного цинку, часу обробки суміші, а також ступеня завантаження кульового млина на ефективність активації полімерної поверхні.
