ISO 23772:2023 Pulps - Kraft liquor - Determination of residual alkali using potentiometric titration
standard by International Organization for Standardization, 03/01/2023
Full Description
This document describes a procedure for determining the content of residual alkali in Kraft blackliquors having a dry matter content up to 40 %.The method is based on a potentiometric titration with hydrochloric acid and is intended for blackliquor samples with an initial pH ≥ 11,0.The lower limit of determination is 0,1 g/l of eq. NaOH.Cart
