The replacement of hydroxyls in kaolinite mineral structure with phosphate anion in the phosphoric acid solution resulted in the formation of sarcopside mineral.
The prepared MLV biomass was subjected to physical-chemical and spectroscopic characterization and then to the analysis of the phosphate anion biosorption efficiency.
The anions chloride, bromide, and iodide were determined by volumetry, whereas the phosphate anion was assessed by spectroscopy with Visible-UV at [lambda] = 720 nm (RAIJ et al., 2001).
The reflux method of CaHAp dissolution to provide phosphate anion in the presence of lead cation succeeds for producing larger sized crystals of the less soluble PbHAp from the aqueous solution.
Phosphate-based materials are well known metal fixing agents in soil through adsorption by phosphate, phosphate anion induced adsorption and precipitation of metals as the phosphates.
During anaerobic muscle contraction ATP is rapidly hydrolyzed to adenosine diphosphate (ADP) and phosphate anion. Phosphorylation of ADP is necessary for the regeneration of ATE There are only minimal ATP stores throughout the body maintained for energy, so when the ATP stores become depleted during the body's muscle contractions, phosphocreatine is then converted into creatine and ATE For an individual to have continuous muscle contraction, immediate regeneration of ATP is necessary.
The third generation is concerned with the substitution of the phosphate anion by the tripolyphosphate one.
This involves chemical reaction of a surface hydroxyl group with phosphate anion species.
The concentration of the inhibitive species in the pigment-saturated solution (phosphate anion and zinc [cation.sup.2]) was obtained according to ASTM D 2448.
In this section, 6 previously published case studies, illustrating the potential value of phosphate anion, liming materials, and biosolids in the immobilisation and the consequent reduction in the phytoavailability of Cd, Cr, and Cu are presented.
Plants acquire phosphorous from soil solution as phosphate anions which are extremely reactive and get immobilized through precipitation with cations such as [Ca.sup.2+], [Mg.sup.2+], [Fe.sup.3+] and [Al.sup.3+], depending on the particular properties of the soil.
The 106 paper discuss such topics as the thermal properties of rigid polyurethane foams treated with flame retardant, removing phosphate anions from wastewater by wasted low-grade iron ore with high phosphorus adsorbent, evaluating thermal properties of fiber insulation materials for inflatable mini cold storage, the simulation analysis of coupled stress field of new silicon carbide brick for metallurgical furnace, optimizing the design of warm extrusion forming technology for piston head semi-processing, and a numerical simulation of the influences of stress and temperature caused by different wire drawing parameters.
