This paper intends to describe a simple and rapid analytical method for polarographic determination of native azo dye-Variamine Blue B Salt. In 0.1 N hydrochloric acid media, the half wave of 0.001 M solution of Variamine Blue B Salt is found at a potential of -0.65 volts (vs. S.C.E.), Increasing pH and concentration of the solution causes a shift of E 1/2 to more negative potential. The height of wave rises as concentration of the solution increases but it drops as pH increases. The presence of...

This paper intends to describe a simple and rapid analytical method for polarographic determination of native azo dye-Variamine Blue B Salt. In 0.1 N hydrochloric acid media, the half wave of 0.001 M solution of Variamine Blue B Salt is found at a potential of -0.65 volts (vs. S.C.E.), Increasing pH and concentration of the solution causes a shift of E 1/2 to more negative potential. The height of wave rises as concentration of the solution increases but it drops as pH increases. The presence of sodium sulfate or zinc sulfate as deluent in the dyestuff does not affect the polarographic wave. This method is applicable for the quantitative analysis of this dyestuff.

重氮鹽类的含量測定,在印染工业方面有其重要的意义和作用。作者試用极谱法分析印染工业上常用的国产偶氮染料——凡拉明藍B鹽,以求得一个簡單迅速的分析方法。以0.1N鹽酸为底液,0.001 M凡拉明藍B鹽在-0.65伏特左右产生一波。它的半波电位与波高随溶液酸度和濃度的改变而异。溶液pH值增高,半波电位負值增加,波高降低。溶液濃度愈高,半波电位負值愈大,波高愈增。应用标定曲綫法可以测定凡拉明藍B鹽的含量。硫酸鈉或硫酸鋅作为填充剂时,对凡拉明藍B鹽的极譜曲綫及波高无多大影响。重氮鹽在高温易于分解,因此操作过程宜在低溫进行。

Utilization of sewage to cultivate green algae has high economic value, and also produces high purification effect on sewage, thus reducing the cost of construction of sewage greatment works.

The quality of water used in the purification of linter pulp exerts a decisive influence on the iron content of the product. Laboratory results show theft the absorption of trivalent iron by de-ashed cellulose possesses the character of surface absorption and obeys Freundlich's equation. At the some concentration, the amount of bivalent iron absorbed is far less than trivalent iron; the mechanism of absorption is also quite different. Based on these informations, proposals aro made for reasonably controlling...

水質对于精煉棉漿含铁量的高低具有决定性的影响。实驗室結果显示,高铁纖維素所吸收系表面吸附性質,且遵从Freundlich吸附规律。在同一濃度时,低鉄的吸收量远较高鉄为小,机理也不同。这些資料对合理控制精煉棉漿的含鉄量頗有帮助。
