Area of Science:

• Analytical Chemistry
• Environmental Science
• Spectroscopy

Background:

• On-site water analysis requires sensitive and simple methods.
• Traditional methods often involve complex sample pretreatment.
• Accurate detection of chemical components at microgram levels is crucial.

Purpose of the Study:

• To develop a new, simple, and sensitive solid-phase spectrometry (SPS) method.
• To enable on-site analysis of targeted chemical components in water.
• To evaluate the universal applicability of the proposed system for real water samples.

Main Methods:

• Development of a solid-phase spectrometry (SPS) system.
• Utilizing a portable spectrophotometer with LED, grating, and CCD.
• Direct analysis of water samples without pretreatment procedures.

Main Results:

• The proposed SPS method demonstrated high sensitivity for water analysis.
• The system successfully determined phosphate, chromium(VI), and iron(II) in natural water.
• The method is applicable to real samples with microg dm(-3) or sub-microg dm(-3) detection levels.

Conclusions:

• The developed SPS is a simple and sensitive technique for on-site water analysis.
• The method's applicability to real samples without pretreatment is confirmed.
• This approach offers a valuable tool for environmental water quality monitoring.
