ABSTRACT:
Methods are provided for treating liquid hazardous waste containing anionic radioactive or heavy metal materials by binding the hazardous waste to hydroxyapatite powder, drying and then cold or hot pressing the hydroxyapatite powder into a solid mass for storage or disposal. The methods are useful for treatment and storage of radioactive waste, anions, and heavy metals. Methods are also provided for treating high concentration liquid hazardous waste and liquid hazardous waste which does not contain materials known to decompose at high temperatures.
