GALACTARATE BASED METAL SEQUESTRATION COMPOSITION

Abstract

A system and method for a metal sequestration composition comprising combining a galactaric salt or galactaric acid with a metalloid oxyanion, and an alkali compound. The system and method enable the production of a metal sequestration composition that either alone or in combination with other functional components (e.g.,, surfactants, solvents, pH modifiers) provide water treatment or cleaning compositions.

Description

Claims
