EPA-1313

Liquid-Solid Partitioning as a Function of Extract pH Using a Parallel Batch Extraction Procedure

Applicability: Method 1313 is used to determine the liquid-solid partitioning (LSP) between water and a solid material at equilibrium over a broad range of pH.

Purpose: Method 1313 test is designed to provide the liquid-solid partitioning curve of constituents as a function of eluate pH. The method consists of parallel batch extractions of solid material, each with an aliquot of either dilute acid or base.
