The surface of the aluminum material usually adopts some chemical methods such as acid treatment to achieve the purpose of improving its protection and functionality, expanding the application range and prolonging the service life. The wastewater produced after the surface treatment of aluminum contains higher concentrations of acid and aluminum ions. It is of great significance to monitor the content of both effectively in terms of production monitoring and environmental protection. In this paper, the new method of temperature titration is used to quantitatively detect H + and Al3 + in aqueous solution. An analytical method is established, and this method is applied to the actual wastewater detection in aluminum plants. The results show that this method has high accuracy and sensitivity, good parallelism, and is convenient and fast.
