1] value of the orthophosphate
resonance measured in a preliminary inversion-recovery experiment.
The dissolved orthophosphate
concentration, measured at the Kasari River gauge since the 1950s (Fig.
The least favorable salts were sodium hexametaphosphate and disodium orthophosphate
because they produced soft, crumbly and mushy textures.
Measurement of inorganic orthophosphate
in biological materials: Extraction properties of Butyl Acetate.
Phosphorous was determined as phosphate using the vanadate phosphomolybdate UV-Visible Spectrophotometric (Shimadzu Corporation, Tokyo Japan, Model UV-3101PC) method where orthophosphate
reacts with vanadate molybdate reagent to form a yellow-orange complex whose absorbance was measured at 420 nm .
Preliminary tests shows that the slimy substance contained D-gluconic acid, a mild acid used to clean metals, and tricalcium orthophosphate
, an additive found in food and fertilizers, Dan Goldblatt, a spokesman for the Department of Environmental Management, said.
The water and sediments samples were monitored for 27 parameters, including total dissolved salts (TDS), electrical conductivity (EC), dissolved oxygen (DO), chloride, total hardness, alkalinity, nitrate, nitrite, ammonia, sulphate, orthophosphate
, total phosphate, biological oxygen demand (BOD), sodium, potassium, calcium, magnesium, cobalt, lead, nickel, chromium, manganese, copper, zinc, cadmium and iron.
The wastewater collected after solid separation was analyzed for total solid (TS), suspended solids (SS), ammonia-nitrogen (NH4-N), orthophosphate
(OP), total Kjeldahl nitrogen (TKN), total phosphate (TP), and total soluble organic carbons (TOCs).
These include hydroxyapatite (HA) and calcium orthophosphate
The remineralising solution used contained 2mM calcium chloride and 2mM sodium dihydrogen orthophosphate
Other initial technological parameters were also determined: C/N ratio, pH, an amount of microorganisms, and contents of ammonium nitrogen and orthophosphate
