Title

Oxalate Influences Rates of Reaction Between Strong Chelating Agents

Presenter

Andrew Wildman

Abstract

Chelating agents are compounds which strongly bind with metals in solution. One chelating agent bonded to a metal can be replaced with another chelating agent under the right conditions. This process is how plants obtain metal nutrients from the environment. In this study, the effect of a third molecule, oxalate, on the exchange between two chelating agents, nickel-NTA and CDTA, was investigated. Several factors that speed up and slow down the reaction are discussed. We propose a reaction pathway and discuss future research objectives.
