Exploring the Phytoremediation Potential of Calotropis gigantea L. Using a Combined FTIR and Principal Component Analysis
Chromium (Cr) is a main concern pollutant and has been recognized to be harmful to fauna, flora, and human beings. The intent of the present study was to investigate the phytoremediation potential of Calotropis gigantea L. plant using a combined FTIR and principal component analysis (PCA) for effective Cr removal. Plant leaves were collected from unpolluted and polluted areas (near tanneries). After authentication, the composite leaf sample of each site was thoroughly washed and allowed to dry. The dried samples were finely powdered and used for FTIR analysis. The FTIR spectra of both the samples showed totally 8 peak values and corresponding 12 functional groups such as alcohols, phenols, alkanes, carboxylic acids, alkynes, alkenes, aromatics, amines, esters, ethers, aliphatic amines, and alkyl chlorides. The peak value’s difference was found to be very low between samples. To confirm this, peak values were subjected to PCA which revealed that no functional groups of both the samples contributing variation were identified. This observation suggests that this plant has a protective mechanism to detoxify heavy metal Cr and could be used for phytoremediation purpose in the future.
