Spectrophotometric determination of cobalt (ii) in low concentrations using hydroxytriazene as selective chelating agents.
Ombaka, O. *; Gichumbi, J. M. (2011-12)The present work describes a selective, rapid and simple spectrophotometric method for the determination of cobalt (II) at trace levels using some selected hydroxytriazene. The method is based on the reaction of hydroxytriazene ... -
Synthesis and Insecticidal activities of some selected hydroxytriazenes
Ombaka, O. *; Gichumbi, J.M. (2012-10)Eight hydroxytriazenes were synthesized and then subjected to spot tests. The composition of these hydroxytriazenes was analyzed using elemental analysis and their physical characteristics like melting point, crystal shape ...
