Exempel på ammonium sulfate

• The sera are then purified by ammonium sulfate precipitation or affinity purification using a peptide column.

• Addition of a neutral salt, such as ammonium sulfate, compresses the solvation layer and increases protein-protein interactions.

• The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

• This is performed by adding increasing amounts of ammonium sulfate and collecting the different fractions of precipitate protein.

• It is an aqueous solution of ferrous ammonium sulfate, sorbitol, sulfuric acid and xylenol orange.

• In the preliminary test, the ammonium sulfate concentration is increased stepwise, and the precipitated protein is recovered at each stage.

• Ammonium sulfate is commonly used as its solubility is so high that salt solutions with high ionic strength are allowed.

• The amount of ferrous ammonium sulfate added is equivalent to the amount of excess potassium dichromate added to the original sample.

• The plant also produces ammonium sulfate, anhydrous ammonia, phenol, cresylic acid, methanol, and naphtha.

• A disadvantage of this approach is the need to dispose of the ammonium sulfate byproduct.

• In addition, ammonium sulfate fertilizer is produced as a byproduct from used reagents.

• The ammonia reacts with the sulfur compounds thus formed to produce ammonium sulfate, which can be used as a nitrogenous fertilizer.

• Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate.

• With trivalent metal ions, alums such as ferric ammonium sulfate are formed.

• The salting out effect is commonly exploited in protein purification through the use of ammonium sulfate precipitation.
