Abstract
A method and composition for the elimination and control of ammonia odor from organic waste materials by contacting the waste material with a composition containing a deodorizing agent which produces a non-odorous ammonia salt, thereby eliminating gaseous ammonia from escaping into the air. The present invention also eliminates additional odors resulting from putrefaction due to ammonia fixing bacteria.
Claims24
A method for controlling and eliminating ammonia odor from organic waste material comprising uniformly contacting said waste material with a composition consisting essentially of an effective amount of an ammonia control component selected from the group consisting of monobasic salts of dibasic acids, and mono-, di- or tri- basic acids, selected from the group consisting of dithionic acid, sulfoxylic acid, formic acid, propionic acid, lactic acid, benzoic acid, ethylenediaminetetraacetic acid, maleic acid, citric acid, malonic acid, succinic acid, malic acid, adipic acid, and furmaric acid, wherein said ammonia control component has a dissociation constant, pK.sub.a, less than the corresponding dissociation constant of aqueous ammonia.
A method for controlling and eliminating ammonia odor from human or animal excreta comprising uniformly contacting said excreta with a composition consisting essentially of an effective amount of sodium bisulfate.
An ammonia odor control composition consisting essentially of an effective amount of an ammonia control component selected from the group consisting of monobasic salts of dibasic acids, and mono-, di- or tri- basic acids selected from the group consisting of dithionic acid, sulfoxylic acid, formic acid, propionic acid, lactic acid, benzoic acid, ethylenediaminetetraacetic acid, maleic acid, citric acid, malonic acid, succinic acid, malic acid, adipic acid, and fumaric acid, wherein said composition has a dissociation constant, pK.sub.a, less than the corresponding dissociation constant of aqueous ammonia, and an absorbent filler material and wherein said composition is physically capable of being uniformly contacted with organic waste material to thereby eliminate and control odors of ammonia emanating therefrom.
An ammonia odor control composition for use on human or animal excreta, consisting essentially of an effective amount of sodium bisulfate as an ammonia control agent in combination with an absorbent filler material, and wherein said composition is physically capable of being uniformly contacted with human or animal excreta to thereby eliminate and control odors of ammonia emanating therefrom.
