STANOVENÍ MAJORITNÍCH MINERÁLŮ V JÍLOVCÍCH A JÍLOVÝCH BŘIDLICÍCH CHEMOMETRICKOU ANALÝZOU INFRAČERVENÝCH SPEKTER

Original language description

The objective of this work is the determination of majority minerals in claystones and clay slates using infrared spectroscopy and chemometric analysis. The chemometric calibration models were developed for the determination of content of chlorite, muscovite, albite and quartz. Diffuse reflectance technique were used to measure the infrared spectra. Principal component analysis (PCA) and partial least-squares (PLS) regression were used as chemometric methods. Spectral regions (4000-2750 cm-1 and 1300-400 cm-1) containing important spectral information were chosen for the creation of the chemometric models. These models were created by a PLS regression method. The value of the mean relative error up to 30 % was found for most of control samples. From the exception of two results, the value of the relative standard deviation up to 5 % was achieved
