cyclohexylidine-ammonium-2-aminocyclohexyline-l-cyclohexee-l- dithiocarboxylate (cccd) is employed for the gravimetric determination of ni (ii). in neutral or ammoniacal solutions, the metal forms a violet precipitate with the reagent which can be weighed as ni (c13h18ns2)a2f ter drying at 115 - 120?c using this procedure, the nickel content of steel samples can also be determined accurately. t...

blood samples were collected from 20 healthy miniature caspian horses at 37 °c. isolation of cryoglobulin was performed based on a standard method in present study. harvested sera were kept at 4 °c for two hours and then examined for cryoglubolin. four serum samples containing precipitate suspicious of containing cryoglobulin were selected. subsequently serum protein electrophoresis was perform...

Abstract: materials can be fabricated by sintering of W-Cu composite powders. In this research W-20%wt Cu composite powderswas synthesized via a co-precipitation method. Precipitate obtained from a mixture of copper nitrate and ammoniumparatungstate (APT) in distilled water contained W-Cu compounds. This precipitate was washed, dried and calcinedat 550 of dried precipitate powder was determined...

processed or melted cheeses are producing in variation kinds because of variety in material blends.using ultrafiltered feta cheese and milk protein co-precipitate in this processed cheese is possible. also, creamy texture of this product is a good and cheaper competitor and substitute for ultra filtered feta cheese that because of creamy texture, more increased its prod. and consumption. also b...
