This study was conducted to analyze the major phytochemicals to evaluate the antioxidant
capacities by using, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities)as well as to
determine the total phenolic, ...
Heavy metals such as lead and cadmium are toxic to environment even in very small
concentration. Thus, a sensitive and selective sensor is required to determine such a very low
concentration. The purpose this work was ...
