A molybdenum (Mo) thiocyanate complex, Mo(SCN)5 had been used previously for the determination of Mo in seawater using electron spin resonance (ESR) method. In the present ESR study, a reduced Mo complex with diethyldithiocarbamate (DDC), Mo-DDC, was extracted with cycohexanol and used for the determination of Mo. Mo-DDC shows a peak at g = 1.980 with peak-to-peak width of 0.3 mT, whereas Mo(SCN)5 shows a peak at g = 1.940 with peak-to-peak width of 1.2 mT. DDC reacts with Mo more specifically than SCN-: The peak height of Mo-DDC is nearly 30 times that of Mo(SCN)5 produced from the solution containing both DDC and SCN- with the molar ratio of DDC: SCN- = 1 : 30. The limit of detection and the time required for measurement are 0.1 ng and 5 min, respectively in the present method, whereas those are 5 ng and 60 min, respectively in the previous SCN method.
