Splet12. apr. 2024 · PCA showed that the chitosan-based ones have the lowest regeneration efficiencies, along with a moderate number of regenerations. NC2, NC9, and G5 are preferred where there is high adsorption energy to the membrane, and high porosities could be tolerated, but this allows lower removal efficiencies of dye contaminants. NC3, NC5, … SpletSpearman, fully equivalent to a classic PCA (based on Pearson correlation) performed on the matrix of ranks. Traditionally, a correlation coefficient rather than the covariance is …
