In early spring 1996 our handbook on science and technology of catalysis will be completed. In order to give all scientists working in the fields of kinetics and homogenous or heterogenous catalysis the possibility to have this detailed treatise of the topic on his or her shelf we decided to offer the whole handbook as a set for a reduced price.

Catalysis science and technology

Since the development of metallopolymers, there has been tremendous interest in the applications of this type of materials. The interest in these materials stems from their potential use in industry as catalysts, biomedical agents in healthcare, energy storage and production as well as climate change mitigation. The past two decades have clearly shown exponential growth in the development of many new classes of metallopolymers that address these issues. Today, metallopolymers are considered to be at the forefront for discovering new and sustainable heterogeneous catalysts, therapeutics for drug-resistant diseases, energy storage and photovoltaics, molecular barometers and thermometers, as well as carbon dioxide sequesters. The focus of this review is to highlight the advances in design of metallopolymers with specific sustainable applications.

FIELD: technological processes.SUBSTANCE: invention can be used for the oxidative neutralization of aqueous process condensates and / or sulphurous alkaline wastewater, contaminated with toxic sulphide and / or mercaptide sulfur, coming from oil, gas, chemical, pulp and paper, metallurgical and leather industries. Method for purification of waste water from sulphide and / or mercaptide sulfur includes their oxidation with air oxygen in the presence of a heterogeneous oxidation catalyst for sulfur compounds on a polymeric carrier. Oxidation of sulphide and / or mercaptid sulfur in effluents is carried out in the presence of a hydrocarbon solvent, which is gasoline and / or kerosene and / or diesel fractions or mixtures based on them.
