摘要:
Ammonium phosphomolybdate (APM) is often used for the adsorption of Cs + . However, the decomposition temperature of cesium-containing ammonium phosphomolybdate waste is low and difficult to dispose of. This study introduces the first use of cold sintering to solidify ammonium phosphomolybdate monomers at low temperatures. The maximum adsorption capacity of the synthesized ammonium phosphomolybdate was 112.58 mg/g. Cold sintering results indicate that the HNO 3 was more effective than other acidic or salt solutions for densifying ammonium phosp...
