H eavy metal (Co۲+, C r۳+, Ni۲+, Pb۲+, Zn۲ +) comple xation by Calixarene, supramolecular nano organic material: chem ometric analysis

Numerous attempts have been made to design new ho st systems which can s electively interact with t he target gu est and perfo rm intrigui ng molecular recognitio n processes [۱].Fine control of the size of calix[n]arenes, bychanging the value of n and the introduction o f var ious f unctional gr oups makes. Calixarene s areof inter est in chromatography, slow release of dr ugs , transport across membranes , ion cha nnelsand many other applications [۲ , ۳].In this research study, stability constants of metal cations and calix[۴]arene and calix[۶]arene in chloroform-methanol (۵۰% -۵۰% v/v) were deter mined at ۲۵°C using sp ectrophoto metric technique.
