SummaryThe coagulation of positively charged sol of hydrous ferric oxide of different average particle sizes by potassium nitrate has been studied. Sensitisation has been observed for ethyl alcohol, acetone and gelatin whilst stabilisation occurs for glucose and urea. The extent of sensitisation decreases with the progress of time whilst the reverse happens in stabilisation. The degree of sensitisation or stabilisation increases with the fineness of dispersed particles. It has been concluded that the adhesive tendency of the surface of dispersed particles is modified in the presence of nonelectrolytes.ZusammenfassungDie Koagulation positiv geladener Sole von wäßrigem Eisenoxid verschiedener mittlerer Partikelgröße durch Kaliumnitrat läßt Sensibilisierung durch Äthylalkohol, Aceton und Gelatine beobachten, während sich für Glukose und Harnstoff Stabilisierung ergibt. Die Sensibilisierung nimmt im Laufe der Zeit ab, während die Stabilisierung steigt. Der Grad der Sensibilisierung wächst mit der Feinheit der Partikel. Es folgt, daß die Adhäsionstendenz der Oberflächen der dispersen Teilchen durch die Gegenwart von Elektrolyten modifiziert wird.
摘要研究了硝酸钾对不同平均粒径水合氧化铁正电溶胶的混凝作用。对乙醇、丙酮和明胶有致敏作用，对葡萄糖和尿素有稳定作用。敏化程度随着时间的推移而降低，而稳定化程度则相反。敏化或稳定的程度随着分散颗粒的细度而增加。结果表明，非电解质的存在改变了分散颗粒表面的粘附倾向。ZusammenfassungDie Koagulation阳性geladener Sole von wäßrigem Eisenoxid verschiedener mittlerer Partikelgröße durch Kaliumnitrat läßt Sensibilisierung durch Äthylalkohol, Aceton und Gelatine beobachten, während sich f r glukse und Harnstoff Stabilisierung ergbt。Die Sensibilisierung niimmt in Laufe der Zeit ab, während Die Stabilisierung stem。Der Grad Der Sensibilisierung wächst mit Der Feinheit Der Partikel。e folgt, daß die Adhäsionstendenz der Oberflächen der分散Teilchen durch die Gegenwart von eleklymodifiziert wind。

SummaryThe coagulation of hydrous ferric oxide sol of varying average particle size has been studied in presence of gelatin for potassium sulphate as the coagulant. The effect of temperature and pH of gelatin solution has been noted. It has been concluded that the surface forces are modified in the presence of gelatin causing sensitisation.ZusammenfassungDie Koagulation von wäßrigem Eisenoxidsol mit unterschiedlicher mittlerer Teilchengröße und Kaliumsulfat als Koagulator wird auf Temperatur und pH der Gelatinelösung untersucht. Die Oberflächenkräfte werden durch die Gelatine im Sinne einer Sensibilisierung modifiziert.
