ISO 11885 Water Quality Determination of Selected Elements by ICP OES
The International Organization for Standardization (ISO) standard ISO 11885 provides a method for the determination of selected elements in water quality using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). This technique is widely used due to its precision, accuracy, and ability to handle complex matrix samples. The primary application area for this standard includes potable water, surface water, industrial wastewater, and other types of water that require stringent chemical analysis.
The method described in ISO 11885 involves several critical steps that ensure the reliability and reproducibility of results:
- Sample Preparation: Proper sample preparation is crucial. Samples must be filtered to remove particulates, which can interfere with the measurement process. Depending on the type of water being analyzed (e.g., raw or treated), additional steps may include dilution or concentration.
- Solution Injection: The prepared samples are introduced into the ICP-OES system via a nebulizer and spray chamber, where they are vaporized in an argon plasma. This process converts elemental species into their atomic forms, which then emit characteristic wavelengths of light that can be detected by the spectrograph.
- Data Acquisition: The emitted light is captured by a CCD camera, and the resulting signal is analyzed to identify specific elements based on their unique spectral signatures.
- Analysis: Calibration standards are used to calibrate the instrument for accurate measurement of analyte concentrations. This involves plotting peak intensities against known concentrations of element solutions.
The standard specifies the use of ICP-OES equipment that meets stringent performance criteria, including limits of detection (LOD) and quantification (LOQ). The LOD is typically in the range of 0.1-1 μg/L for most elements, while the LOQ can be as low as 0.5-2 μg/L depending on the element being analyzed.
One key advantage of ISO 11885 is its ability to target multiple elements simultaneously in a single measurement cycle. This makes it particularly efficient for testing water samples that contain several contaminants of concern, such as heavy metals like lead (Pb), cadmium (Cd), and mercury (Hg). The standard also allows for the detection of trace amounts of these elements, which is critical for ensuring compliance with drinking water quality guidelines.
Compliance with ISO 11885 ensures that water samples are analyzed under controlled conditions, leading to consistent results across different laboratories. This is particularly important in regions where there is a need for uniformity in water quality standards and monitoring practices.
The method described in ISO 11885 is not only applicable to the chemical analysis of water but also plays a crucial role in environmental protection efforts, public health initiatives, and industrial processes. By providing accurate data on elemental concentrations, this standard helps stakeholders make informed decisions regarding water treatment, pollution control, and resource management.
