Phosphorus Extraction from Fish Waste Bones Ash by Acidic

Sep 17, 2019· The worldwide demand of phosphorus (P) is rising rapidly; however phosphate ores are not renewable. Fish bones contain high amounts of P, but hardly recycled or reused. Therefore, this study investigated P extraction from fish waste bones by acidic leaching method. The study shows that P content in fish bones ash is around 17 wt.%.

Phosphorus recovery from the biomass ash: A review

Oct 01, 2011· As an alternative to phosphorus rock, phosphorus can be recycled from phosphorus-rich residues, such as meat and bone meal (MBM), municipal sewage sludge, phosphorus-rich ashes, agricultural residues, etc.. The plant nutrients such as phosphorus, potassium, magnesium, and sodium, are nearly completely recovered in the agriculturally usable ash

Phosphorus recovery from sewage sludge char ash

Jun 01, 2014· Phosphorus recovery from char combustion ash obtained at 900 °C is higher than phosphorus recovery from char combustion ash obtained at 600 °C and at 750 °C, under the same extraction conditions. However, the yield of phosphorus from the ash obtained at the three combustion temperatures studied is similar when using oxalic acid.

Chemical phosphorus recovery from waste fish bones ash by

The phosphorus content in the fish bone ash represents around 17 wt.%. The potential of phosphorus recovery from waste fish bone ash by chemical dissolution was investigated in this study. Different amounts and concentrations of sulfuric acid (H2SO4) was applied to determine the optimum condition of phosphorus extraction.

Phosphorus Wikipedia

Historically, before the development of mineral-based extractions, white phosphorus was isolated on an industrial scale from bone ash. In this process, the tricalcium phosphate in bone ash is converted to monocalcium phosphate with sulfuric acid: Ca 3 (PO 4) 2 + 2 H 2 SO 4 → Ca(H 2 PO 4) 2 + 2 CaSO 4

Power of two methods for the estimation of bone ash of

Mar 01, 2003· The R2 for g bone ash is much higher than for % bone ash (0.918 vs. 0.568; Table 4). The variability in weight of the bone ash is mainly attributable to day, phytase level, and method R2 = 0.918), but other bone components left after water and lipid removal (organic matrix) must not be attributable to these factors.

ANALYSIS OF ASH AND MINERALS UMass

4. Analysis of Ash and Minerals . 4.1 Introduction. The “ash content” is a measure of the total amount of minerals present within a food, whereas the “mineral content” is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and Cl.Determination of the ash and mineral content of foods is important for a number of reasons:
