The utilisation of the phosphorus in spent bone charcoal by young wether sheep

Abstract

Spent bone charcoal from a sugar refinery was compared with dicalcium phosphate as a source of phosphorus for young sheep given a low phosphorus diet. The apparent digestibility of both forms of phosphorus was similar. Dicalcium phosphate and spent bone charcoal supplementation resulted in positive phosphorus retentions of + 0.61 and f0.90 g P/day respectively compared with a daily loss of -0.29 g P/day for the low phosphorus diet. Both forms of phosphorus addition increased blood phosphorus concentrations.

Granulated Activated Carbon Modified with Hydrophobic Silica Aerogel-Potential Composite Materials for the Removal of Uranium from Aqueous Solutions

“…The activity of the GAC-aerogel composites fall roughly in the middle of the materials listed in the table. The 17% H 3 PO 4 modified composite has activity similar to bone charcoal, which is consistent with both materials having phosphate sites ( , ) . Alumina has nearly an order of magnitude higher capacity but is generally more expensive and does not usually work in GAC canisters.…”
