Abstract:
A slow-release solid-chemical composition for environmental remediation which provides a sustained-release of organic substrates and complex inorganic phosphates, said sustained release being for a period of at least twenty-four hour, comprising:a. a source of soluble organic substrates selected from the group consisting of sugars, soluble organic polymers and combinations thereof, in an amount of from about 7% to 90%, by weight percent, of said composition; b. substantially insoluble organic substrates selected from the group consisting of fibrous plant materials, starches, cellulosic materials and combinations thereof, in an amount of from about 10% to 7%, by weight percent, of said composition; c. complex inorganic phosphates selected from the group consisting of ringed metaphosphates, linear polyphosphates and combinations thereof, in an amount of from about 0.5% to 7%, by weight percent, of said composition; and d. soluble organic salts selected from the group consisting of lactates, formates, acetates, sorbates, citrates and combinations thereof, in an amount of from about 2% to 70%, by weight percent, of said composition.
