摘要:
研制适用于高温燃烧氧化-非分散红外吸收法的总有机碳(TOC)分析仪高温反应单元.该系统利用立式管式炉内侧的镍烙丝对石英管和石英管中的石英棉和催化剂进行加热,炉内安置K型热电偶,用于检测石英棉和催化剂的温度,管式炉外径达到130 mm,以保证保温性能.系统工作温度设定为680 ℃,以保证催化燃烧效果.分别在蜂窝陶瓷上进行,负载质量分数为0.5%的Pd和0. 07%的Pt两种催化剂测试.实验结果显示:这两种催化剂都能完全催化氧化TOC质量浓度为40 mg·L-1的邻苯二甲酸氢钾和蔗糖有机物溶液;对TOC质量浓度高达1 000 mg·L-1的试样,Pt催化剂效果稍稍优于Pd催化剂.
Abstract:
Temperature catalytic oxidation reactor of total organic carbon(TOC)analyzer using temperature catalytic oxidation technique and non-dispersive infrared absorption method is developed. The system includes high temperature tube furnace, K type thermocouple, quartz tube, quartz wool and noble catalysts. The operation temperature is set to 680 ℃, in order to ensure the catalytic efficiencies. 0.5%(mass fraction)Pd and 0.07%(mass fraction)Pt loaded on honeycomb ceramic are selected as noble catalysts. The experiments show that KHP and sucrose can be fully oxidized by Pd and Pt catalysts when TOC concentrations are 40 mg·L-1. Pt catalyst is more effective than Pd catalyst when TOC concentrations are 1 000 mg·L-1. The sample in which TOC concentration up to 1 000 mg·L-1 can be fully oxidized and detected demonstrate that the TOC analyzer using Pt catalyst has high applicability.
