Method for manufacturing high purity ammonium dihydrogenphosphate using ammonium phosphate waste solutions

摘要

The present invention relates to a method for manufacturing high purity monoammonium phosphate using ammonium phosphate waste liquid. According to the present invention, monoammonium phosphate, which has at least 98% (w/w) purity in powder form can be manufactured from ammonium phosphate waste liquid. Thus, the present invention reduces environmental pollution by recycling ammonium phosphate waste liquid and has an advantage of obtaining monoammonium phosphate with high yield and low cost by a simple manufacturing process.
