|
The determination of hydrazine and its derivatives has received much attention recently because of their
involvement in areas such as chemical and pharmaceutical industries, fuel cells, explosives, propellants, rocket fuel,
insecticides and oxygen scavengers for corrosion control in boilers and hot-water heating systems [1, 2]. Among several
analytical methods such as ion chromatography, chemiluminescence, spectrophotometry, high performance liquid
chromatography and electrochemical methods, electrochemical methods are low cost with rapid response and have
some advantages like high sensitivity and selectivity for determination of various compounds like hydrazine [3]. In the
present work homemade bulk modified screen printed electrode based on Pd|SiC nano particles was used as a high
sensitive electrochemical sensor for hydrazine detection in real samples. Polyol-reduction method was used for the
synthesis of Pd nano-particle on SiC substrate. The prepared nano catalysts were characterized by using SEM, TEM,
BET and XRD techniques. Next the sol-gel method was used for screen printing of catalyst at the surface of glass
electrode. After preparation of modified screen printed electrode the electrochemical properties of it was studied by CV
technique. Finally the prepared sensor was used for detection of trace amounts of hydrazine in drinking water and rain
water samples with a good recovery and precisions.
