AB Batch experiments were used to test P sorbent potential of soil samples, pyritic and granitic materials, mussel shell, mussel shellash, sawdust, and slate waste fines for different pH and incubation times. Maximum P sorption varied in a wide range of pH: < 4for pyritic material, 4–6 for forest soil, > 5 for slate fines, > 6 for shell ash, and pH 6–8 for mussel shell. P sorption was rapid(< 24 h) for forest soil, shell ash, pyritic material, and fine shell. On the opposite side, it was clearly slower for vineyard soil,granitic material, slate fines, pine sawdust, and coarse shell, with increased P sorption even 1 month later. For any incubationtime, P sorption was > 90% in shell ash, whereas forest soil, pyritic material, and fine shell showed sorption rates approaching100% within 24 h of incubation. These results could be useful to manage and/or recycle the sorbents tested when focusing on Pimmobilization or removal, in circumstances where pH changes and where contact time may vary from hours to days, thus aidingto diminish P pollution and subsequent eutrophication risks, promoting conservation and sustainability.
