Spectrophotometric simultaneous determination of nickel, cobalt and copper by orthogonal signal correction–partial least squares
A method for the simultaneous spectrophotometric determination of nickel, cobalt and copper based on theformation of their complexes with 2-(2-Thiazolylazo)-p-Cresol (TAC) in micellar media of Triton X-100 isproposed. The absorbance spectra were recorded in the range of 500 to 800 nm. The linear concentrationrange for nickel, cobalt and copper in solution calibration sets were 0.05–1.80, 0.10–6...
متن کاملDetermination of Protein and Moisture in Fishmeal by Near-Infrared Reflectance Spectroscopy and Multivariate Regression Based on Partial Least Squares
The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

متن کاملBiosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
متن کاملChemical and bioanalytical applications of surface enhanced Raman scattering spectroscopy.
Raman spectroscopy is a highly versatile physicochemical technique that provides vibrational fingerprints from chemical and biological materials. The Raman spectrum that arises from the interrogation of chemical species can be readily interpreted and used to identify specific chemical species in mixtures and to quantify their levels accurately. However, the non-resonance Raman effect is very we...
