Aplicabilidad de la técnica de espectroscopia de reflectancia en el infrarrojo cercano para determinar dodecilbenceno sulfonato de sodio y humedad en detergente en polvo

In this work it was explored the use of near infrared reflectance spectroscopy (NIRS) to determine the sodium dodecylbenzene sulfonate and moisture in powder detergent. Calibrations equations were obtained by applying partial least squares regression due to the presence of the spectral interferences. Matrix effect was verified. Accuracy and precision of this method is acceptable, indicating that the NIRS methods can be applicable for determining moisture and sodium dodecylbenzene sulfonate in powder detergent.
