摘要

•PLS and SVM models were developed for the determination of mesopore volume of alkali-treated ZSM-48 zeolites.•The orthogonal signal correction significantly affected the predictive ability of the PLS model.•Comparable results were obtained using the two models-OSC-PLS and SVM with lower RMSEP for SVM.•BET and DRIFT had no significant difference by applying OSC-PLS and SVM.
