Data for the Determination of Total Carbon in Biosolids using MID-Infrared Spectroscopy

Area of Science:

• Environmental Science
• Analytical Chemistry
• Spectroscopy

Background:

• Biosolids analysis requires accurate determination of total carbon.
• Conventional methods like Dumas combustion are effective but can be costly and time-consuming.
• Development of alternative, cost-effective analytical techniques is crucial for environmental monitoring.

Purpose of the Study:

• To present data for developing a methodology for total carbon determination in biosolids.
• To evaluate the efficacy of Mid-Infrared (MID-IR) spectroscopy combined with Partial Least Squares (PLS) for this analysis.
• To compare the performance of the MID-IR-PLS method against conventional techniques.

Main Methods:

• Utilized Partial Least Squares (PLS) regression analysis.
• Employed Mid-Infrared (MID-IR) spectroscopy for spectral data acquisition.
• Developed and validated a calibration model for total carbon quantification in biosolids.

Main Results:

• The MID-IR spectroscopy combined with PLS demonstrated a reliable method for total carbon determination.
• The developed method was found to be an acceptable and inexpensive alternative to the Dumas combustion method.
• The LECO C analyser, a conventional method, was used as a benchmark for comparison.

Conclusions:

• MID-IR spectroscopy coupled with PLS is a suitable and economical method for quantifying total carbon in biosolids.
• This approach offers a practical alternative for routine analysis in environmental laboratories.
• The findings support the adoption of spectroscopic methods for efficient biosolids characterization.
