Structural Insight into Chitosan Supports Functionalized with Nanoparticles

Figure 6

PCA biplot of CH and nanocomposite matrices in the ATR-FTIR region 1700–1400 cm⁻¹ (a). PCA score plots show the cluster distribution of nanocomposites formulated with different N:CH ratios for N_A (b) and N_B (c). Correlation between the absorbance corresponding to 900 cm⁻¹ and the concentration of tripolyphosphate (C_TPP) obtained from PLS model (d). Figure inserted in figure (d) shows predicted versus measured values.
