Spectrophotometric studies on nickel complex of 3-hydroxy-3- phenyl 1-1-0-carboxyphenyl triazene

D N PUROHIT, JESUS BLANCO

Abstract


Nickel  forms  a  1:1  yellowish green  complex  with  3-hydroxy-3-phenyl-l-0-carboxyphenyl triazeneat  pH  6.0-  7.7.  The  complex  has  lamda  max  at  414  nm  with  molar absorptivity  and  Sandell' sensitivity  indices as  3.14X  1^4  1  cm^-1  mole^-1  and 0.0018  ug/cm^2  respectively.  It  has  been  found  to  be a  sensitive reagent suitable for nickel(II) estimation.
