 note = {In order to evaluate the alkali elution rate from MSW incineration bottom ash after a long time has passed, a sequential leaching test of 6 sizes of sieved ashes was conducted with nitric acid as a solvent. In order to reduce pH rapidly, the pH ofthe solvent was stepwise changed to 1.7, 2.7 and 4. After changing the pH of the solvent to 4, the pH of the leachate remained constant at about 4 where the leaching time was 1 day, and the pH of the leachate remained at about 7 where the leaching time was more than 2 days, with each particle size of bottom ash. The total alkali elution rate (RA) was affected by the leaching time. RA remained constant at 2* 10^-2 mmol/g/d where the leaching time was 1 day, and at 4-6* 10^-3 mmol/g/d where the leaching time was more than 2 days with each particle size. The total released alkalis reached the saturation point of 0.03-0.04 mmol/g.},
