ÐèÒªÈóÉ«µÄ²¿·ÖÈçÏ£º Aiming at the shortcoming of the traditional methods, active exploration and some extent breakthrough have been obtained by many researchers abroad. This paper reviews the most recent research progress of the determination methods of C, including mainly two parts: the improved and optimized methods according to the standard ones, and new technologies and methods. The former may shorten the detection time significantly, and reduce the costs, but they can not avoid the environmental pollution by the chemical reagents, and have insufficient oxidation ability to the refractory organics. New detection techniques which are different from the traditional methods, such as f, c, o, e ones or a combination of several techniques, can further shorten the detection time, and dramatically reduce the pollution of the reagents. With the development of the science and technology, new methods have been developed recently and are reviewed in this paper, giving reference for the accurate, rapid, low-cost and on-line monitoring determination of C.

| But the environmental pollution by the chemical reagents is still unpreventable meanwhile and oxidation ability to the refractory organics is not sufficient. New detection techniques which are different from the conventional one, such as f, c, o, e ones or a combination of several these techniques are also reviewed. Deection time can be further reduced, and the pollutions casued by the reagents are also drastically reduced. With the development of the science and technology, new approaches have been presented as a reference for the accurate, rapid, low-cost and on-line monitoring of C concentration in the water. |
