The abundance of urea in the natural environment is dictated by the fact that it is one of the major products of mammalian protein metabolism. Due to the extensive use of urea in many branches of industry, it is produced in large quantities. Urea enters into the environment not only with wastewater from the production plants but also by leaching from the fields, agro-breeding farms, and the effluents from the plants using it as a raw material. There are many methods of urea removal, but most of them are still being developed or are very new. The methods themselves differ in terms of physicochemical nature and technological ingenuity. Many wastewater treatment methods include processes such as hydrolysis, enzymatic hydrolysis, decomposition in the biological bed, decomposition by strong oxidants, adsorption, catalytic decomposition, and electrochemical oxidation. In this work, methods of urea removal from aqueous solutions have been reviewed. Particular attention was paid to electrochemical methods.

Alicja Kazek-KęsikWojciech SimkaIn this work, a review of the literature concerning the surface modification of implants composed of titanium and titanium alloys by plasma electrochemical oxidation (PEO), also known as micro-arc oxidation (MAO), is presented. The application of this process allows for the formation of oxide layers with different porosities on implants. Moreover, it is possible to enrich these oxide layers with species contained in solutions used for anodising, yielding suitable surface chemical properties. Anodising titanium implants in solutions containing compounds of calcium and phosphorous leads to the formation of bioactive layers and significantly reduces the time required for the osseointegration of implant to bone. Studies of the PEO process with respect to titanium implants have been conducted by a large number of research centres, and their results have been applied to the production of a new generation of titanium implants.

About Me
Prof. Wojciech Simka, Ph.D., is an employee of the Faculty of Chemistry at the Silesian University of Technology. He serves as head of the Department of Inorganic, Analytical and Electrochemical Chemistry; head of the Corrosion Research Laboratory; and chairman of the Chemical Engineering Discipline Council. He serves or has served as the head of research projects funded by the Ministry of Science and Higher Education, NCN, NCBiR. His research interests are related to the modification of the surface layer of metals by electrochemical methods, particularly in terms of biomedical applications. He focuses on electrochemical oxidation, both classical and high voltage plasma electrolytic oxidation (PEO), of materials based on titanium, tantalum, zirconium, niobium and magnesium. His current focus is on plasma electrolytic oxidation of printed titanium implants (personalized implants and scaffolds). He is the author of more than 180 JCR-listed articles, as well as more than a dozen patents. Solutions developed by his team have been implemented in several industrial plants in Poland.
