SPECTROPHOTOMETRIC DETERMINATION OF Cu(II) AND Ni(II) USING 4 PHENYL-3-THIOSEMICARBAZONE OF 2-HYDROXY-4-n- PROPOXY-5-BROMOACETOPHENONE (HnPBAPT) AS ANALYTICAL REAGENT (original) (raw)

Sector-125, NOIDA-201303, INDIA @amity. I. Introduction Thiosemicarbazones have been used for spectrophotometric determination of various metal ions like iron[1], palladium[2], cobalt[3], Vanadium[4] etc. Cu(II) has been individually determined by complexing agents like Oxime[5-8] along with other thiosemicarbazones[9]. Similarly Ni(II) also has been determined individually using oximes[10]. Determination of both Cu(II) and Ni(II) has been done using biladiene[11], thiosemicarbazones[12], 5-methyl-2-furaldehyde thiosemicarbazone[13], isatin-p-thiosemicarbazone[14], substituted salicylaldehyde thiosemicarbazone[15], semicarbazone and thiosemicarbazone of 2-hydroxy-4ethoxy acetophenone[16], oxime[17] etc.
