Derivative spectra, Back return of derivative spectra, Visual Basic, data treatmentAbstract
Derivative spectrophotometry is one of the analytical chemistry techniques used
in the analysis and determination of chemicals and pharmaceuticals. This method is
characterized by simplicity, sensitivity and speed. Derivative of Spectra conducted
in several ways, including optical, electronic and mathematical. This operation
usually be done within spectrophotometer. The paper is based on form of a new
program. The program construction is written in Visual Basic language within
Microsoft Excel. The program is able to transform the first, second, third and fourth
derivatives of data and the return of these derivatives to zero order (normal plot).
The program was applied on experimental (trial) and reals values of sulphate
determination in the form of barium sulphate by a Linear Array Ayah 5SX1-T-1DCFI Analyser. The data was collected through an Array M3500A 6.5Digit Digital
Multimeter linked between the spectrometer and computer.
