Overview

ASTM D6827 is a standard test method for preparing floor polishes and similar polymers for the analysis of total zinc content by Flame Atomic Absorption Spectroscopy (FAAS).

Determination of zinc content is essential for assessing product quality, wear resistance, compliance with environmental standards, and disposal procedures for used floor finishes. The procedure can provide accurate measurements of zinc content, even at low concentrations.

Scope, Applications, and Benefits

Scope

Test Process

Sample Preparation & Acid Digestion

Samples are homogenized, dried, ground, and digested with nitric acid.

Dilution

The digest solution is diluted to fall within the calibration range.

Instrument Calibration & Measurement

FAAS is calibrated with zinc standards, and absorbance is measured at 213.9 nm.

Data Analysis

Zinc concentration is determined from the calibration curve.

Frequently Asked Questions

Zinc compounds improve floor polishes' durability, wear resistance, and film integrity. Monitoring zinc content ensures product performance and regulatory compliance.

While ASTM D6827 focuses on zinc, FAAS can be adapted to measure other metals by selecting appropriate wavelengths and conditions.

Matrix effects, spectral overlaps, and ionization can interfere with zinc measurement. Background correction and matrix matching minimize these issues.

The detection limit for zinc by FAAS is typically in the low μg/L range, making it suitable for trace-level analysis.

Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) or ICP-Mass Spectrometry (ICP-MS) provide higher sensitivity and multi-element analysis but are more expensive.
