|Title:||1,3-Bis(salicylidineamino)thiourea dehydrate as an analytical reagent for the direct spectrophotometric determination of Co(II) in natural samples|
|Authors:||Prabhakar, L D|

|Abstract:||A simple, rapid, selective and sensitive spectrophotometric method for the determination of microamounts of Co(II), alone or in presence of associated metals has been developed. Co(II) forms a 1:2 complex with 1,3-bis(salicylidineamino)thiourea dihydrate which obeys Beer's law in the concentration range of 0.1 to 100 ppm of Co(II). The molar absorptivity and Sandell's sensitivity of the method are 1.8924 x 104 dm3 mol-1 cm-1 and 0.049 μg cm-1 respectively.|
