| Short description: |
Research used a gel prepared from the waste products of orange juice production. This contains around 10 per cent pectin, which can be converted to pectic acid with the addition of calcium hydroxide. When ions of zirconium are added to the gel, it shows strong adsorption of phosphates. After use, treating the gel with sodium hydroxide then removes around 95 per cent of the adsorbed phosphorus. This means that both the gel and the phosphorus can be re-used. Tests showed that the gel remained effective, even when it had been used many times.
