我校化学系和北京有色金属与稀土应用研究所合作,研究成功的“一种新型钍显色剂”最近荣获国家三等发明奖。这是我校获得的第六个发明奖。我校化学系研制出了80多种新有机化合物拟作钍显色剂,经过筛选,在国内外首次研究成功性能优异的新型钍显色剂6,8—萘二磺酸偶氮氯膦及其测钍的直接光度法。随后,化学系和北京有色金属与稀土应用研究所合作,共同开发研究了该发明的推广应用。该发明的性能指标优于目前国内外测定钍广泛应用的、先进的偶氮胂Ⅲ等钍显色剂及其方法,其灵敏度为1.89×10~5,高于偶氮胂Ⅲ(1.1—1.3×10~5);选择性好,对主要常见元
Our chemistry department and the Beijing Institute of Nonferrous Metals and Rare Earth Applications, the successful research “a new thorium developer” recently won the third prize of national invention. This is the sixth invention award my school won. Our chemistry department has developed over 80 kinds of new organic compounds to be used as thorium chromogenic agents. After screening, the new thorium chromogen 6,8-naphthalenedisulfonic acid chlorophosphonates and their The direct photometric method of measuring thorium. Subsequently, the Department of Chemistry and Beijing Institute of Nonferrous Metals and Rare Earth Cooperation, jointly developed and studied the promotion and application of the invention. The performance index of the invention is superior to the currently widely used and advanced thorium color developing agents such as arsenazo Ⅲ and the like, which have a sensitivity of 1.89 × 10 -5 and higher than that of arsenazo Ⅲ (1.1-1.3 × 10 ~ 5); good selectivity, the main common element
