| titleOfInvention | pretreatment method for analyzing catalyst |
| abstract | Pretreatment method for vehicle catalyst analysis according to the present invention is a process for dissolution after filtering by adding aqua regia (hydrochloric acid: nitric acid = 3: 1) and hydrogen fluoride (HF) mixture, the precipitate filtered after dissolution by adding aqua regia and hydrogen fluoride mixture Na A process of melting with 2 O 2 , a process of filtering after only aqua regia, and a process of melting with a Na 2 O 2 after filtering the aqua regia, and analysis of Rh, Fe, P, and Ti is performed in the first step. By the process, the analysis of Pt and Zr is carried out by the second process or the fourth process, and the analysis of Ce, Ba, Ca, Mg Zn and Al is carried out after the pretreatment by the third process or by the fourth process. There is an effect to effectively analyze the included metal components. |
