The Emerging Issue of Using Rice Straw-Derived Carbon Material in Detecting Abused Weight Medication

Abstract

In this work, the experimental test is concentrated on developing a modified electrode – RTAC-modified GCE. RTAC or activated carbon extracted from rice straw would be applied to modify the bare GCE. This modified electrode would detect an abused pharmaceutical in feedstock - Terbutaline (TEB). The electrochemistry method employed in the test is a differential pulse anodic stripping voltammetry (DP-ASV). The DP-ASV analysis outcomes described that TEB would be determined with good selectivity and high sensitivity on RTAC/GCE, expressing a defined peak at 515 mV. The LOD – limit of detection and LOQ – limit of quantitation of TEB in this paper were calculated to be 0.237 µM and 0.782 µM, leading to the RTAC/GCE application in detecting TEB being ensured. It could be understood that the employed sensor is optimal to apply to find the analyte due to its fabulous selective and sensitive properties.
