Abstract
Zirconium compounds reduce odors. Zirconium hydroxide and sulfated zirconium are especially efficient at reducing the odors of primary, secondary and tertiary amines or ammonia. Zirconium hydroxide and/or sulfated zirconium may be incorporated in pads which are the recipients of odoriferous waste materials, dispersed in holding tanks or lagoons or dispersed over human and animal wastes.
