Approach to green chemistry is an essential aspect in academic and industrial research laboratories. Recent developments showed that, there are many challenges in environmental awareness and issues of sustainability in the world. Many experiments involving many hazardous chemicals which are not safe to human health and environment. In Industries and laboratories various hazardous and costly chemicals are used for separation of metals from multicomponent mixture and this method is useful to acheive 100% purification & separation with better yield by using green procedure. We have developed rapid, easy and an operationally simple, inexpensive, efficient method from readily available reagents in laboratory mostly by taking a view of green approach. It includes Introduction to Poly-(DB-18-Crown-6) as Green stationary phase, protocol for its Green approach and Result discussion for Protocols followed. Further Development of protocols for separation of some other commercially important samples are under progress. We take opportunity to thank to Principle Dr. C. G. Yeole, Janta Shiksahan Santha,wai for providing necessary facilities and encouraging us.
