To optimize the reaction conditions in order to evaluate the effect of potassium dihydrogen phosphate
as catalyst screened for the model reaction (Table 1).
The concentration of sodium dihydrogen phosphate
is also a key factor in CPE .

in China," Phosphate Compound Fertilizer, vol.
First, 11.1 g of sodium dihydrogen phosphate
, 22.2 g of sodium hydrogen phosphate and 0.8 g of peroxide hydrogen were dissolved in 160 mL of distilled water, and then, 40.0 g of starch was added to the mixed solution.
Sodium hydroxide was purchased from Fluka (Poole, UK) and potassium dihydrogen phosphate
from Sigma- Aldrich (Poole, UK).
Chitosan interactions with halides and dihydrogen phosphate
solutions studied in this paper may be expressed by the equation 4:
The above chemical reaction shows that bacterially produced sulfuric acid attacked on insoluble tricalcium phosphate and converted it into soluble and bio-available dihydrogen phosphate
(Kumar and Nagendran 2008; Bhatti and Yawar 2010).

Potassium dihydrogen phosphate
(KDP), with good physical properties including large nonlinear optical coefficient, good structural quality, and mechanical properties, is used in many large-aperture laser systems as frequency conversion crystal and electrooptic switching.
The process parameters such as the fermentation period (24-96 h), pH (6.0-10.0), moisture content (60%-140%), inoculum size (3%-15%), carbon sources (1%, w/w) (maltose, sucrose, starch, glucose, xylose, and trehalose), nitrogen sources (1%, w/w) (casein, yeast extract, peptone, beef extract, gelatin, and urea), and inorganic salts (ammonium chloride, sodium dihydrogen phosphate
(Na[H.sub.2] P[O.sub.4]), calcium chloride, sodium nitrate, disodium hydrogen phosphate ([Na.sub.2] HP[O.sub.4]), ammonium sulphate, and ferrous sulphate) were evaluated.
The functional monomer of Clearfil SA Cement is the 10-methacryloyloxydecyl dihydrogen phosphate
(10-MDP), which is able to form a strong and stable ionic bond with calcium from hydroxyapaptite.
Sodium-, potassium-, ammonium- dihydrogen phosphate
, sodium hydroxide and methanol were obtained from Merck KGaA (Darmstadt, Germany), and ortho-phosphoric acid ([H.sub.3]P[O.sub.4]) (85%) from Riedel-de-Haen (Seezle, Germany).
To the filtered water 10 ml of 10% pot dihydrogen phosphate
, 2 ml of cal[cl.sub.2] and drops of ammonia solution is added and it is left for a night.
The basal fertilizer was applied 700 kg-[ha.sup.-1] compound fertilizer (N:[P.sub.2][O.sub.5]:[K.sub.2]O=15:15:15) and 20 [m.sup.3]-[ha.sup.-1] chicken manure, seed fertilizer 50 Kg-[ha.sup.-1] ammonium dihydrogen phosphate
, and 50 kg-[ha.sup.-1] trace elements fertilizer (Cu + Fe + Mn + Zn + B + Mo [greater than or equal to] 10%).
