The Computer Realization Of Portends Coulomb Analysis

Portends coulomb analysis is under specific conditions, with the current 100 % efficiency, Using Hang Electrical potential, to electrolyte the measured material measure electrolytic currents under different time, combine the linear relationship between current number and electrolytic time, measure the straight line's slope and quadratic cut rule, calculate the aggregate material according to faraday electrolytic law.This paper explored the main factors and the possible interference factors of Portends Coulomb Analysis, identified experimental conditions election and optimization criteria: number of current and time strictly obey linear relationship, at the same time the quantity of measured material reached to the requirement of chemical measurement error; Raised the way of choosing portends coulomb analysis conditions such as acidity, electrode area, electrolytic electrical potential, shelter agent of options, established, an experimental method for portends coulomb analysis.Portends Coulomb analytical instruments designed well. Using VB language programming achieved the combination of (The Least Two Multiple method) current number and electrolytic time through The Least Two Multiple method, established the experimental database, fulfilled experimental database storage, retrieval and comprehensive analysis. The related graphics can be mapped on the basis of experimental data. Using of data processing systems for the processing experimental data show that: the system functional and simple to operate, it can satisfy. The signal portends coulomb analysis of data processing requirements.Compared with other coulomb analysis methods, Portends Coulomb Analysis needn't fully electrolyte the measured substance, if use the automatic sampling system, appropriate control electrolytic conditions, it can instantly get the analytic result, greatly reducing the analysis time and improve the efficiency, At the same time, because coulomb analysis are all absolute analysis methods, when the method is established, expensive standard samples are not needed to analysis actual sample, greatly reducing the use and emissions of harmful chemical reagents, and thus the use of law has a good economic and environmental benefits, as well as it has a wide range of applications. In the building of saving, environment-friendly society...
