本文是以X荧光光谱分析的方法测定铝基铂催化剂中的铂的含量。此法适用于较高含量的测定。一、实验部分(一)仪器日本岛津VF—320X荧光光谱仪;DP—32联用控制、微处理机;36吨压片机(日本岛津);远红外烘箱(装有水银导电表自动控温)。(二)制样方法准确量取待测溶液6毫升,用3克DE—22纤维素吸附,在烘箱中65℃温度下烘干,用玛瑙研钵研细(250—400目),研匀,然后
This article is based on the X-ray fluorescence spectrometry determination of the platinum content of aluminum-based platinum catalyst. This method is suitable for higher content determination. First, the experimental part (a) instrument Japan Shimadzu VF-320X fluorescence spectrometer; DP-32 with control, microprocessor; 36 tons tablet press (Shimadzu); far infrared oven (equipped with mercury conductive automatic control temperature). (B) sample preparation method accurately measure 6 ml of solution to be tested, with 3 grams of DE-22 cellulose adsorption, drying in an oven at a temperature of 65 ° C, finely ground with an agate mortar (250-400 mesh) ,then
