    • Methods of treating animal litter and/or bedding material for control of volatile ammonia and soluble phosphorous include applying granular partially hydrated ferric sulfate to the litter. The partially hydrated ferric sulfate ranges from gray to tan in color and is spread onto the litter at a rate effective to reduce ammonia volatilization and reduce soluble phosphorous. Relative to reagent grade ferric sulfate, the partially hydrated ferric sulfate exhibits lower hygroscopicity and higher deliquescence. The ferric sulfate is prepared by a process comprising oxidizing ferrous sulfate with sulfuric acid using a molecular oxygen oxidizing agent at an elevated pressure relative to atmospheric and at a temperature of 60° C. to 140° C. to produce a gray to tan colored granular product.
    • 用于处理挥发性氨和可溶性磷的动物垃圾和/或床上用材料的方法包括将颗粒状部分水合的硫酸铁应用于垃圾。 部分水合硫酸铁的颜色从灰色到棕褐色,并且以有效减少氨挥发和减少可溶性磷的速率传播到垫料上。 相对于试剂级硫酸铁,部分水合硫酸铁表现出较低的吸湿性和较高的潮解性。 硫酸铁是通过一种方法制备的,其中包括使用分子氧氧化剂,在相对于大气压的升高的压力和在60℃至140℃的温度下用硫酸硫酸亚铁硫酸亚铁,以产生灰至褐色的颗粒状 产品。
