Science frontier - Cu content in copper for quick detection theory of one of the pluripotent spectrophotometry

Number of visits: Date:2010-6-25

Determination of the content of Cu in copper - "a pluripotent visible spectrophotometry"

 

60 s photometric method, provides may not separation and simultaneous determination of several components, more important is that it also provides the use of ultraviolet and infrared wavelengths are analyzed. Spectrophotometric analysis of range, however, has never been beyond the boundaries of "low concentration", this will severely limit the spectrophotometry in daily application of industrial analysis.

Daily analysis, accurate, convenient, rapid, economic and security are the basic principles of evaluation method. In the 80 s, some scholars, experts have begun to study spectrophotometry extended application in routine analysis, in the 90 s, there are scholars put forward the "one method of pluripotent visible spectrophotometry" - test a high concentration of "residual photometric method", for the majority of enterprises lab daily analysis made cannot be underestimated.

Pure copper for electrolytic method commonly, so also called electrolytic copper, because its color is purple, so it is also called copper. High content of Cu in copper, the analysis of the traditional method is to use constant current electrolysis method, because of its complex analysis steps, analysis cycle is long and cannot meet the requirements of routine analysis, and USES the "residual spectrophotometry to detect the contents of Cu in copper, the testing time only need 10 minutes, and only need regular chemical reagent, using appropriate masking agent will be a lot of Cu masking, in NJSB - 5 b computer intelligent fast analyzer to choose the appropriate wavelength, colorimetric cup, the percentage of the prototype can direct reading Cu.

Due to heavy usage of residual reagents in photometric method, therefore, high precision, better reproducibility in accuracy can reach 0.05%, the accuracy can meet the requirements of the analysis precision of red copper. It can also be used pure determination of lead and zinc.
