Wet Chemical Analysis

Wet chemical analysis involves identifying and quantifying the desired elements present in a liquid sample using several methods. It can be divided into two main types, the qualitative analysis identifies the elements and the quantitative analysis determines the quantity. With chemical reagents, the analyte can be used to convert a dye proportionally, which can be read-out visually or photometrically.

The wet chemical analysis comprises a multitude of techniques, including titration, distillation, spectrophotometry (UV/Vis/IR), colorimetry, filtration, drying, weighing, pH tests, and direct read with electrodes. These methods of analysis may be more labor-intensive compared to other methods as automation can’t be applied to some of these techniques.

  • pH Measurements
  • BOD Determination
  • COD Determination
  • NP Analyzers
  • TOC Analysis
  • Dissolution/Digestion
  • Gravimetric Analysis

FULL WIDTH TEXT SAMPLE

pH quantifies the amount of free hydrogen and hydroxyl ions present in the water and therefore, the pH value (0-14, 7 being neutral) indicates the acidity and alkalinity of a solution. pH measurement is the most significant test performed in laboratories as many of the physical, chemical, and biological processes are dependent on pH. The pH measurement using pH meter gives the most accurate results. A pH meter measures the voltage difference between two electrodes when dipped in a solution. Standard buffer solutions are used for calibration of the pH meter to produce reliable and reproducible results.

BULLET POINTS

Biochemical oxygen demand (BOD) measures the amount of dissolved oxygen consumed by microorganisms in the aerobic decomposition of organic matter from water. BOD determination estimates the amount of biodegradable organic matter present in wastewater, effluent, and polluted waters. The two widely used methods for BOD measurement are the dilution method and the manometric method.

  • Dilution method: This is a standard method wherein the sample (dilution water) is prepared by adding inorganic nutrients, buffer salts, and sufficient amounts of bacteria to purified water. Several dilution levels of the sample are then prepared. The BOD bottles are filled to the top, capped, sealed, and incubated in the dark at 20 °C for 5 days. The dissolved oxygen levels are measured before and after the 5-day incubation period. The difference in these two values, corrected for the dilution and the blank, is the BOD5 value.
  • Manometric method: In this method, a manometer is fitted into a bottle that contains an undiluted sample. It continuously monitors the air pressure drop inside the bottle, which reflects the amount of oxygen uptake by the sample. This method is easier than the dilution method since no dilution is required, and continuous measurements are achievable.
