Major environmental pollutants include heavy metals which are toxic and bio accumulative nature. The commonly found heavy metals in waste water include cadmium, chromium, copper, and zinc, all of which cause risks for human health and therefore the environment. It's essential to have a general understanding of the essential principles for various methods of elemental analysis. Atomic absorption spectroscopy (AAS) techniques were chosen to assess their suitability for the determination of several heavy elements in complex environmental and biological samples. Pre concentration of copper involving different techniques like solid-phase extraction, co- precipitation and liquid–liquid extraction (LLE), cloud-point extraction are used. This study is review of determination of copper by AAS .This article provides a summary of the foremost sensitive techniques of determination of copper by AAS.
