Abstract

Highlights: Coriandrum Sativum leaf was characterized by FESEM, FTIR and TGA/DSC. FTIR analysis revealed the presence of -OH groups, C-H stretching of alkanes. C. Sativum leaves can be a promising green biosorbent for polluted water treatment. Abstract: This study aims to investigate the potential of Coriandrum Sativum leaves as a green biosorbent. The produced biosorbent was characterized by Field Emission Scanning Electron Microscopy (FESEM), Fourier-Transform Infrared Spectroscopy (FTIR) and Thermogravimetric analysis/ Differential Scanning Calorimetry (TGA/DSC) analyses. FESEM results indicate the formation of irregular shapes with non-uniform distribution. FTIR analysis revealed the presence of –OH groups, C–H stretching of alkanes, and amide areas that are characteristics of proteins and enzymes. TGA/DSC specifies the weight loss after 340 °C is attributed to the degradation of lignin cellulose and hemicelluloses content in C. Sativum . Results from the characterization indicates that the use of C. Sativum leaves can be a promising green biosorbent for the treatment of polluted water owing to its low cost and highly availability.
