Synthesis of Dodecaaza-Tetra-chloro-tricyclodotri- acontane macro cyclic complexes of (Cu ++ ) transition metal ions present in pulp and paper mill effluents

Heavy metal ions has been receiving a great attention in the recent years, as
the high concentration of toxic metal ions This paper deals with short review and to
study the various types of heavy metals present in waste water released from Pulp and
Paper effluents. These are being constantly poured into the environment, which result in
the long lasting bio-hazards in the aquatic eco-systems. So it is new technique of estimating
Cu, Ni metals present in Pulp and Paper effluents .The investigation incorporates in the
physio chemical properties of some new divalent Cu (II), Co (II) and Ni (II), metal ion
macro cyclic complexes. The investigation includes their synthesis and spectral magnetic
properties.
