Classification of Titrimetric Analysis Based on Reaction Types

Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.
Titrations between an acid and a base lead to neutralization reactions that form...

PloS one·2025

Chemometric data mining, including factor analysis (FA), cluster analysis (CA), and discriminant analysis (DA), effectively identified water quality patterns in the Kinta River. This approach can simplify long-term water quality monitoring by reducing variables and stations.

Area of Science:

  • Environmental Science
  • Data Science
  • Water Resource Management

Background:

  • Water quality monitoring is crucial for assessing river health.
  • Understanding spatial variations in water quality is essential for effective management.
  • Chemometric techniques offer powerful tools for analyzing complex environmental datasets.

Purpose of the Study:

  • To apply chemometric data mining techniques to a water quality dataset from the Kinta River, Malaysia.
  • To identify key water quality parameters and their influencing factors.
  • To classify monitoring stations based on water quality characteristics and assess the potential for monitoring optimization.

Main Methods:

  • Factor Analysis (FA) was used to identify underlying factors influencing water quality variations.

  • Cluster Analysis (CA) grouped monitoring stations with similar water quality profiles.
  • Discriminant Analysis (DA) confirmed the clusters and developed a predictive model for station classification.

    • Main Results:

    • Factor analysis highlighted weathering and surface runoff as significant contributors to Kinta River's water quality.
    • Cluster analysis delineated two distinct groups of monitoring stations: low pollution (upstream) and high pollution (mid- to downstream).
    • Discriminant analysis successfully validated these groupings and provided a function for classifying new samples.

    Conclusions:

    • Chemometric techniques are effective for uncovering the structure within water quality data.
    • The study demonstrates the potential to reduce the number of water quality variables and monitoring stations for efficient long-term monitoring.
    • Findings provide a basis for targeted water resource management strategies in the Kinta River basin.
