9. Analysis Methods – Organics in Water
The chapter focuses on the analysis of organics in water, particularly highlighting extraction methods to recover contaminants at low concentrations. Key aspects include the process of liquid-liquid extraction using immiscible solvents, the implications of using hazardous chemicals, managing interferences during analysis, and the importance of filtration and suspended solids analysis. It emphasizes the need for careful method selection and waste management in environmental monitoring.

What we have learnt
- Extraction is essential for isolating organic contaminants at low concentrations.
- Liquid-liquid extraction techniques utilize compatible, immiscible solvents to concentrate analytes.
- Proper filtration is critical to avoid interference in the analysis of target compounds.
Key Concepts
- -- LiquidLiquid Extraction
- A method for separating compounds based on their solubility in two different immiscible liquids.
- -- Interference
- The presence of other substances that can affect the analysis of a target analyte.
- -- Total Suspended Solids (TSS)
- A measure of solid particles suspended in water, determined by filtering a water sample and weighing the solids.
- -- Filtration
- The process of separating solids from liquids by passing the mixture through a filter.
- -- Hazardous Chemicals
- Substances that pose a risk to health or the environment and require proper management and disposal.
