Standard Test Method for Determination of Metals in Purified Terephthalic Acid (PTA) by Inductively Coupled Plasma Atomic Emission Spectrometric Method

Importancia y uso:

4.1 The presence of metals in PTA used for the production of polyester is undesirable because they may speed up or slow down the reaction and be impurities in the final product.

4.2 Determination of the metals in PTA is often required. This test method is suitable for setting specifications and for use as an internal quality control where these products are produced or used.

4.3 This test method covers the determination of sodium, chromium, cobalt, aluminum, titanium, potassium, magnesium, manganese, iron, nickel, molybdenum, and calcium.
