Synthesis of Dodecaaza-Tetra-chloro-tricyclodotriacontane 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.
