Description

Cyanide, Releasable, For RCRA Compliance is a specialized chemical standard designed for environmental testing and regulatory adherence. This product is critical for laboratories and facilities that must accurately quantify and report cyanide levels to meet stringent environmental regulations. It is primarily used by analytical chemists, environmental consultants, and industrial compliance officers in wastewater treatment, mining, and chemical manufacturing sectors to ensure accurate monitoring and reporting.

Application

• Environmental Compliance Testing: Used as a standard for the analysis of free cyanide and cyanide amenable to chlorination in water and wastewater, as mandated by regulations like the US EPA's RCRA and Clean Water Act.
• Wastewater Treatment Monitoring: Essential for process control and effluent monitoring in industrial plants to ensure discharge limits are met.
• Mining and Metallurgy: Employed in the analysis of process streams and tailings to monitor cyanide usage and environmental impact in gold and silver extraction.
• Forensic and Hazardous Waste Analysis: A key reference material for identifying and quantifying cyanide in contaminated soil and forensic samples.
• Quality Assurance/Quality Control (QA/QC): Serves as a calibration standard and control sample in analytical laboratories to validate test methods (e.g., ASTM, ISO, SM 4500-CN).
• Industrial Hygiene and Safety: Used to calibrate monitoring equipment for workplace air quality and safety assessments in relevant industrial settings.

Quality Control

Our Cyanide, Releasable, For RCRA Compliance standard is manufactured and tested under strict quality protocols to ensure traceability, accuracy, and consistency for critical environmental analysis. Each batch is analyzed against NIST-traceable reference materials using validated methods such as titration or ion-selective electrode (ISE) to confirm concentration and stability. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing assay value, uncertainty, expiration date, and storage conditions to support your laboratory's ISO 17025 accreditation and data integrity requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C). Keep away from strong alkalis and fluorides. For maximum stability and to prevent photodegradation, the solution should be stored in amber glass or opaque containers.
