[en] The installation of straight unit and evaporator, the improvement of mixing blade could be reduced a drying time and had no trouble in maintaining a drying process of borate waste. In plastic solidification of powdered cation exchange resins, a sound waste forms was obtained above 33.2 wt% of their water content. And according to the increase of their water content, the compressive strength of waste forms was decreased. The degradation rate of spent cation exchange resins by using Fenton's reagent was 87.6% in reaction condition of resin/hydrogen peroxide = 0.095, 0.065 M Fe⁺². And the study on wet oxidation of anion exchange resins is needed for treatment of mixed resins furthermore. The ratio of unsaturated polyester/cement in a composite waste forms was about 0.075 for a good workability, curing time and mechanical properties. (Author)
