TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The caustic products comprises sodium hypochlorite, potassium hydroxide, ammonium hydroxide, ammonium tetramethyl hydroxide, lithium hydroxide, calcium hydroxide, magnesium hydroxide, barium hydroxide, cesium hydroxide, strontium hydroxide, rubidium hydroxide and/or copper hydroxide. The treatment is carried out using compounds such as brass, copper, aluminum, carbonized steel, polyurethane and nylon. The fluids include helium, neon, argon, krypton, xenon, nitrogen, hydrogen, oxygen, ozone, fluorine and/or hydrogen chloride. The inert gases include nitrogen, argon and helium. Preferred Method - The NaOH is introduced in the form of atoms using an ultrasonic spray nozzle to break up the NaOH solution into very fine droplets that effectively disseminates in the complex geometries of the external surfaces of contaminated materials, and added in the form of fine solid powder to form a NaOH aerosol in the chamber at climatic conditions of 5-95% using air or neutral gas. When the composition is formed, a vacuum between initial stage and ultrahigh stage is created and NaOH solution (0.001-30 vol.%) having a concentration of 2-10 M is added to attain a total content of 20-400 kg/hour, a vapor tension of 18-200 Torr, a temperature of 31-60 degrees C and a pressure of 73-300 bars. The microparticles and nanoparticles are formed by dissolving the NaOH solution in an organic apolar solvent such as alcohols and then introducing under pressure to a lower opening present in the chamber filled with CO2 in dense state. The fragile and high pressure sensitive material is protected by adding a first NaOH solution to the contaminated material to the chamber, adding dense CO2 in the chamber without expanding the NaOH solution at 73-300 bars, and maintaining a constant pressure of 73-300 bars and a temperature of 40-60 degrees C inside the chamber. The decarbonation/carbonation steps are obtained by depressurization/pressurization or decompression/compression steps by hydrophobic gas/liquid separation membranes. Liquid/gas contact membranes are arranged for diffusion of gas in the microscopic liquids. The decarbonation is performed in the chamber by decompression/compression using hydrophobic gas-liquid separation membrane leaving CO2 in the chamber under pressure and to maintain NaOH solution, adding inert gases to the composition to replace CO2, moderately increasing the temperature above 70 degrees C, and performing ultrasonic or megasonic treatment having a frequency of 20 kHz to 1 MHz and 1-100 MHz. The rate of depressurization/pressurization is 10-100 bars/hour. The rate and time of decompression/compression is 1-10 cycles/hour and 30 minutes to 1 hour and the variation in pressure is 1-10 bars. The agitation unit comprises magnetically coupled agitator with an electric motor or directly connected to an electric motor, a rotating drum magnetically coupled to the electric motor, an engine connected directly to a power by a shaft passing through the wall of an autoclave, jets, a fluid recirculation unit, a heating unit and bubbles in the fluid. Acetic acid, paracetic acid and hydrochloric acid are added to the composition for rinsing. Essential antimicrobial oils are extracted on the place of CO2 in dense state from natural or animal vegetable sources, which are introduced in the separation chamber. Disinfectant or sterilizing additives with antiaggregating-, chelating- and surface active agents are added to the composition for optimizing inactivation of the microorganisms. The degree of elimination and inactivation of contaminants is carried out at an operating time without corroding the material to be treated, base disinfecting level, intermediate disinfecting level, and top disinfecting level to obtain the level of sterility corresponding to an existing probability of living microorganisms of 10-6. The treatment is carried out using anionic surfactants or nonionic detergents, oils, enzymes such as proteases thermostable alkaline, hydrogen peroxide and sodium hypochlorite.
