高灵敏新希土显色剂偶氮氯膦-mA技术鉴定及分析交流会于1979年12月1日至3日在上海建国饭店召开。参加会议的有来自全国各地的科研及厂矿企业64个单位,代表103人。会议代表听取了上海师范大学、浙江省机械科学研究所、杭州汽车发动机厂三个主办单位所作的关于“高灵敏新希土显色剂偶氮氯膦-mA的合成及其在光度分析中的应用”的报告。同时,山东省机械设计研究院,鞍山钢铁公司质量监督处中心试验室,湖南邵阳汽车发动机厂等单位分别在大会上对该显色剂的应用作了交流。代表们通过试用和现场实样试验,认为新希土显色剂偶氮氯膦-mA是成功的,是一种尚未见国外报导的新希土显色剂,它具有灵敏度高、选择性好、稳定性好、操作简便等特点.会议通过了偶氮氯膦-mA的技术鉴定书。
High Sensitive Neo-earth color reagent chlorophosphonazo-mA technology identification and analysis exchange meeting was held December 1, 1979 to 3 in Shanghai Jianguo Hotel. Attend the conference, there are 64 units from scientific research, factories and mines around the country, representing 103 people. Conference delegates listened to the synthesis of the chlorophosphonazo-mA with high sensitivity and sensitivity to neodymium-chromophore-AA synthesized by three host organizations of Shanghai Normal University, Zhejiang Institute of Machinery Science and Hangzhou Automobile Engine Factory and their photometric analysis Application "report. At the same time, Shandong Machinery Design and Research Institute, Anshan Iron and Steel Company Quality Supervision Center Laboratory, Hunan Shaoyang Automotive Engine Factory and other units at the General Assembly on the application of the developer made a communication. Representatives through the trial and field test, that the new Xituo reagent chlorophosphonazo-mA is a successful, is a new gentiopicr has not yet been reported abroad, it has high sensitivity, good selectivity , Good stability, easy operation, etc. The meeting passed the chlorophosphonazo-mA technical appraisal.
