- •
Pine bark has a very low retention capacity for phosphate, arsenate or fluoride.
- •
In turn, pine bark removal capacity for dichromate was very high.
- •
Large differences between anions suggest different retention mechanisms for each one.
- •
Dichromate retention might proceed through reduction to Cr(III) and precipitation.
