Pollution Abatement: Reclamation of Red Phosphorus Smoke Composition
Abstract
Investigations leading to safe, ecologically-permissible disposal of red phosphorus smoke compositions have been completed and have resulted in a laboratory demonstration of methods for disposing of and reclaiming the pyrotechnic ingredients used in signals containing red phosphorus compositions. Laboratory test data are provided which demonstrate that pyrolusite, one of the ingredients in the waste composition, is not manganese dioxide as commonly thought in the pyrotechnic field. It is recommended that the nitric acid dissolution process be utilized in the pilot plant phase. This process produces a solution which, when adjusted to pH=8 using concentrated ammonium hydroxide solution, provides a soil additive solution.
