Research Aim: To characterise the partitioning of polar organic contaminants to the adsorbent material Oasis HLB® as a function of pH and ionic strength:

  • The application of polymers plays a critical role in the analysis of organic contaminants

  • The relative affinity of the chemical to the polymer in the sorbent-liquid system is key parameter for both SPE and passive sampling

  • Target compounds include 21 compounds classed as priority substances in the EU water framework directive

  • Therefore, the equilibrium sorption behaviour of a range of organic contaminants to Oasis HLB® in aqueous systems at environmentally relevant concentrations was investigated

  • Oasis HLB® is one of the most commonly used sorbents for solid phase extraction (SPE) and polar organic chemical
