• 中文摘要： 本文係以一均混出料結晶槽探討鉀明礬在不同雜質影響下之結晶動力學,雜質種類包括一離子(Cr/sup 3+/),一分散劑((NaPO/sub 3/)/sub 6/)及一有機染料(俾斯麥克,棕色)。鉀明礬之晶體成長及成核速率之雜質效應雖各有不同,包括增大、減少或不變,但兩者之變化卻是一致。但在含固量及滯留時間相同之條件下兩者之變化相反,所預測之動力學行為與實際者相符。
• 英文摘要： An MSMPR crystallizer was used to study the crystallization kinetics of potassium alum in the presence of impurities. Three different types of impurity, including an ionic species (Cr/sup 3+/), a dispersing agent((NaPO/sub 3/)/sub 6/), and an organic dye (Bismarck Brown), were tested. Although various effects of impurities on the crystal growth and nucleation rates were observed, the responses to the addition of impurity for crystal growth and nucleation rates were in the same direction; no matter they were increasing, decreasing, or remaining unchanged. However, under the constraint of constant magma density and retention time, different kinetic behavior, that is, the addition of impurity causes the crystal growth and nucleation rates to respond in an opposite direction, for the same system was concluded.
