Key Points

The proposed method enables direct measurement of dissolved reactive phosphorus in porewater, enhancing accuracy compared to ex-situ methods.
By integrating digital imaging with diffusive gradients in thin-films, this approach significantly reduces labor in phosphorus analysis.
Employing phosphomolybdenum blue improves the sensitivity of detecting dissolved reactive phosphorus levels in sediment.
This innovative technique's in-situ capability addresses common errors associated with concentration changes during sample handling.

Implication

This method measures dissolved reactive phosphorus in sediment porewater, indicating potential for more accurate in-situ analysis than traditional methods.

Abstract

Current methods for determining dissolved reactive phosphorus (DRP) in sediment porewater mainly rely on ex-situ analysis, which can be labor-intensive and introduces errors due to changes in the concentration and...
