摘要

Abstract

In this paper

we propose that the urinary toxins from the wastewater be adsorbed on an adsorbent such as spherical activated carbon and the latter be regenerated by subjecting it to high temperatures to recycle activated carbon and also to recycle the water used in dialysis. We studied the adsorption of artificial waste dialysate

which is a mixed solution of urea

creatinine

and uric acid

and the separate solutions for each of these and found that their extents of adsorption onto the spherical activated carbon material were nearly identical. The amount of adsorption was approximately 1.4 mg·g

-1

for urea

18 mg·g

-1

for creatinine

and 20 mg·g

-1

for uric acid. The urea

creatinine

and uric acid adsorbed onto the spherical activated carbon decomposed on heat treatment at 500℃

and the adsorption capacity of the spherical activated carbon was regenerated. Our study successfully demonstrated that the spherical activated carbon can be recycled in the waste dialysate treatment process.
