A system and a solution-preparation-determining apparatus which determines whether additional preparation of an undiluted dialysate solution is necessary. A blood purification system includes a solution-preparing unit that prepares an undiluted dialysate solution, a dialysate-supplying unit that prepares a working dialysate at a predetermined concentration by diluting the undiluted dialysate solution received from the solution-preparing unit, a blood-purification-treatment section that includes a blood-purification-apparatus group including at least one blood purification apparatus that performs blood purification treatment in which the working dialysate is supplied to the blood-purification-apparatus group, and a determining unit that determines whether additional preparation of the undiluted dialysate solution is necessary from a result of comparison between an estimated number of treatment sessions expected to be performed by the blood-purification-apparatus group throughout a predetermined period and an actual number of treatment sessions performed by the blood-purification-apparatus group as of a time point during the predetermined period.

A catalyst for purification of exhaust gases comprising: a support substrate; an active alumina coating layer comprising at least one of nickel oxide and cobalt oxide formed on the surface of the support substrate; a composite oxide comprising cerium oxide and zirconium oxide formed in the active alumina coating layer; and noble metal catalyst ingredients comprising at least one of platinum, palladium and rhodium loaded on the active alumina coating layer. The catalyst offers a decreased hydrogen sulfide H.sub.2 S emission and conversion ratios for hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxides (NOx) equivalent to or superior to those of conventional catalysts.
