Standard Operating Procedure for the Laboratory Analysis of Lead in Paint, BulkDust, and Soil by Ultrasonic, Acid Digestion and Inductively Coupled Plasma Emission Spectrometric Measurement

摘要

The details and performance of a simplified extraction procedure and analysis forthree media are provided. Paint, bulk dust, and soil are collected using standard or referenced methods. Up to 0.25 g of paint, bulk dust, or soil weighted out and placed in a 50-mL centrifuge tube. Five mL of 25% (v/v) nitric acid is added and the sample is ultrasonicated for 30 minutes.
