| description | The relevance of the study is caused by the need to develop new methods for the disposal of metal waste. This direction, with the participation of various intensifying effects, refers to resource-saving, technological, minimizing the volume of capital costs for raw materials, production and subsequent sales.
Purpose: to study the physical and chemical laws of aluminum waste acid processing in the field of ultrasound, propose a mechanism for this process, and, based on the established laws and the proposed mechanism, develop a method for aluminum waste acid processing to obtain reaction products that are in demand in the industry.
Objects: samples of aluminum waste in the form of plates and shavings.
Methods: volumetry, differential thermal analysis, evaluation and analysis of the kinetic curves of the process at different temperatures.
Results. The kinetic curves were analyzed, the rate constants of the process at different temperatures were calculated, and the order of the chemical reaction was found. Based on the calculated activation energy of the process, a characteristic was given about the kinetic region of the process. The mass content of aluminum in the samples was found. According to the data obtained, exposure of the system to ultrasound contributed to an increase in the rate of the chemical process by 90 % at 303 K; by 5 % at 313 K. The process itself began within 10...30 seconds and completed within a few minutes, which confirms the possibility of recycling aluminum waste using acid solutions at low temperatures. The resulting hydrogen can be used in hydrogen energy, since it is the only gaseous product of the reaction, which eliminates the need for its purification before transportation. The aluminum chloride solution synthesized during the reaction can be used in wastewater treatment, wood processing, production of antiperspirants, as well as precipitated aluminum phosphate and used in the ceramic industry. |
