• Strategic Value: Improves go/no-go decisions for adsorbent selection by enabling rapid, cost-effective screening of multiple variables (pH, kinetics, competing ions).
• Portfolio Impact: Supports risk-adjusted advancement by quantifying adsorption limits and identifying conditions where buffer interference is negligible (e.g., 10 mM buffers).

Implementation Considerations

• Requires expertise in phosphorus digestion chemistry and spectrophotometric analysis at 880 nm.
• Needs access to a thermostat capable of 148–150 °C and spectrophotometer with 880 nm filter.
• Demands standardization of buffer preparation (e.g., 10 mM MES/CAPSO/acetic acid) and phosphonate stock solutions (1 g P/L).
• Requires adaptation of K₂S₂O₈ and NaOH dosages based on buffer-specific COD to ensure complete digestion.
• Limited to samples where phosphorus concentration falls within or can be diluted to match the ISO_mini calibration curve.
