Abstract
En 中文
This study depicts the effective synthesis of graphitic carbon nitride (GCN) and sulfur doped graphitic carbon nitride (S-GCN). The prepared GCN and S-GCN were subjected to various characterisation techniques to investigate the surface functionality and crystalline nature with the XRD and FT-IR respectively and surface properties were analysed with the SEM and EDX. This assisted the development of a novel and well modified nanohybrid with incorporation of multiwalled carbon nanotubes i.e. S-GCN/MWCNTs/GCE for the electrochemical detection of antibiotic clindamycin phosphate over the potential range of 0.6V to 1.1V against the silver/silver chloride electrode with the detection and quantification limit of 1.88 x 10(-7) M and 6.62 x 10(-7) M respectively. Various inorganic ion and organic molecules did not interfere with the clindamycin phosphate during its sensing. Additionally, the developed S-GCN/MWCNTs/GCE nanohybrid can be applied to real sample and environmental sample analysis and holds the potential for broad applications in the CMP sensing.
