Description
Rumbidzai Mugwira tried to recover phosphorus from bay mud dredged at Malmfjärden, Kalmar, in a 2026 early-stage study. The goal was strong phosphorus release with as little metal contamination as possible.
Single washes used citric acid, sulphuric acid, sodium hydroxide or EDTA at two strengths, with acidity also varied in some runs. Stronger mixes and more acidic settings usually pulled out more in the reported results, and sulphuric acid at pH 1 freed the most phosphorus at 46.4% of content. EDTA also performed well, and a two-step wash was tested to balance yield against purity.
