Phosphorus Concentration Determination

This experiment determined the concentration of phosphorus in two different water samples, alpha (α) and theta (∆), using both Persulfate Digestion Method for Total Phosphorus and Acid Hydrolysis for Condensed Phosphates. The analysis revealed a significantly higher phosphorus concentration in sample alpha compared to theta. Both samples exhibited an absorption wavelength of 690nm. A strong correlation between light absorption with regard to cobalt (II) chloride and the phosphorus concentration was observed, highlighting the effectiveness of spectrophotometry for accurate measurements.

1.0 Conclusion
The objective of this experiment was realized because the assessment allowed for the
determination of phosphorus concentration in the different water samples. The concentration of
phosphorus was different for samples alpha (α) and theta (∆). Moreover, the concentration of
phosphorus in sample alpha was considerably greater than that observed in sample theta. Under
both assessment methods (Persulfate Digestion Method for Total Phosphorus and Acid
Hydrolysis for Condensed Phosphates) the wavelength of both samples was 690nm. The linear
regression method allowed for easy computation of absorption given the concentration level.
There is a strong correlation between the absorption of light with regard to cobalt (II) chloride
and the concentration of phosphorus in the water sample. The spectrophotometer was used to
eliminate the errors in the wavelength assessments.
