Synthesis of Calcium Oxalate Particles Using Emulsion Liquid Membrane (ELM): Effect of Extractant Concentration on Morphology

Harsh Bharatkumar Shukla

Abstract: There are three hydrate forms of Calcium oxalate which are crystallized in different morphologies and the natural occurrence is connected with the three minerals whewellite as (COM) monoclinic monohydrate, (COD) weddilite as orthorhombic dehydrate and (COT) caoxite as triclinic trihydrate. Emulsion Liquid Membrane (ELM) systems is a useful tool for quick and selective removal of metals from dilute aqueous streams. Calcium oxalate used as filler and a pigment in coated paper and the cardboard industry to impart brightness.
