EPA-3005A

Acid Digestion of Waters for Total Recoverable or Dissolved Metals for Analysis by Flame Atomic Absorption (FLAA) or Inductively Coupled Plasma (ICP) Spectroscopy

Applicability: EPA Method 3005A is a standard method for acid digestion of water samples to prepare them for the analysis of total recoverable or dissolved metals using Flame Atomic Absorption (FLAA) or Inductively Coupled Plasma (ICP) Spectroscopy.

Purpose: The primary purpose of Method 3005A is to ensure that metals in water samples are in a suitable form for analysis by specific analytical techniques (FLAA or ICP). It is used for preparing both surface and ground water samples for the determination of total recoverable or dissolved metals.
