Simulation ammonium nitrate

Initiation with only one portion of ceric amnoniiM nitrate (rather than with two portions added one hour apart) reduces both the conversion of monomer to polymer and the water absorbency of the fined product. Based on these results, starch in future reactions was gelatinized by heating for 60 min at 95 C, to more closely simulate conditions of continuous steam jet cooldng 02) r %diich would be used commercially. Also, polymerizations were initiated with two portions of ceric ammonium nitrate dissolved in IH HNQs, seponification mixtures were stirred continuously rather than intermitt Ttly (as a matter of convenience), and absorbent polymers were dried at 40 C.

A combination of measurements and simulations have indicated that cloudwater sulfate, acidity, nitrate, and ammonium deposition exceeds wet deposition via precipitation for some NE U.S. sites located above 400 m. While the current large uncertainties that are associated with cloudwater deposition models make firm estimates impossible, the available data indicate that cloudwater deposition is a substantial contributor to wet deposition inputs to high elevation sites in the eastern United States. Similar conclusions have been reached by European studies.
