recovery from manure dosing iron

Anticipated start: January 2023

Duration: minimum 4 months

Location: Wetsus Research Institute, Leeuwarden, the Netherlands

P-recovery from manure? That’s the shit!

Selectively removing phosphorus (P) from manure and using it as a secondary resource in phosphate related industries would be an option to decrease P levels in agricultural soils. This project focuses on a fundamental understanding to recover P from manure dosing iron (Fe). Depending on the matrix, the amount of Fe necessary to form the iron phosphate vivianite is different. Since organic matter and sulfides have been identified as possible Fe sinks, the aim is to investigate their interactions with Fe in different matrices (manure, sewage sludge, lake sediment).


You will study vivianite formation and dissolution in different conditions and matrices.

Your tasks include:

  • Studying vivianite formation and dissolution in different conditions
  • Brainstorming to develop the project
  • Prepare samples for a wide range of analytical techniques such as ICP-OES, Mössbauer spectroscopy, ATR-IR, NMR
