The Prediction of Adsorption Properties of a Solid Phase-Microextraction Fiber by Chemometrics methods
Journal Title: Advanced Journal of Chemistry-Section A (Theoretical, Engineering and Applied Chemistry) - Year 2019, Vol 2, Issue 3
Abstract
A new method for estimation of adsorption properties of a solid phase micro extraction fiber by artificial neural network (ANN) has been studied for the first time ever. An etched steel fiber which is simple prepared and durable was selected and adsorption of 12 analytes that were in four different chemical categories, was studied. 9 of them were selected as the training and 3 as the test. The amount of adsorptions were obtained through the direct extraction from aqueous and then GC analysis. The adsorption were analyzed by ANN. The results are quite satisfactory and the mean absolute percentage error of tests was 18.0 %. The method was simple, practical, straightforward, economical, and accurate. The method did not require many analyses.
