ISO 16772 Nickel Determination Test in Effluent
The ISO 16772 standard provides a comprehensive framework for determining nickel content in effluents, which is crucial for industries that discharge water into the environment. This test ensures compliance with environmental regulations and helps minimize ecological impact. The process involves several critical steps, including sample collection, preparation, digestion, and final analysis.
Sample Collection:
- Ensure representative samples are collected from the discharge point
- Preserve samples at 4°C until analysis
- Document all sampling procedures meticulously
Preparation:
The effluent sample must undergo digestion to release nickel ions for accurate measurement. This typically involves acidification and heating under controlled conditions, ensuring the stability of nickel species.
Digestion:
1. Acidify the sample with nitric acid (HNO₃) or a mixture of nitric and perchloric acids.
2. Heat the sample to 90°C for digestion.
3. Allow cooling, then filter if necessary to remove any particulates.
Analysis:
The nickel content is determined using atomic absorption spectroscopy (AAS) or inductively coupled plasma optical emission spectrometry (ICPOES). These methods provide high precision and accuracy, allowing for the detection of trace amounts of nickel. The results are reported in parts per million (ppm).
Acceptance Criteria:
The effluent must comply with the specified limits set by local regulations or international standards such as ISO 16772. Non-compliance may result in fines and operational disruptions.
This test is essential for industries including steel manufacturing, electroplating, and metal finishing, where nickel discharge into water bodies can have significant environmental impacts.
