对在双水相气浮浮选测定四环素(TC)的含量中,选择正丙醇作有机溶剂,氯化钠作分相剂,氢氧化钠(盐酸)溶液调节酸度,将TC与Ca(Ⅱ)形成的疏水性缔合物浮选至有机相,浮选完毕后经分光光度法分析。本文考察和分析了配位数、pH值、浮选时间对双水相气浮浮选的影响,得出浮选最佳条件:pH值9.5,浮选时间为6 min,n(Ca2+):n(Tc)=1∶1。
對在雙水相氣浮浮選測定四環素(TC)的含量中,選擇正丙醇作有機溶劑,氯化鈉作分相劑,氫氧化鈉(鹽痠)溶液調節痠度,將TC與Ca(Ⅱ)形成的疏水性締閤物浮選至有機相,浮選完畢後經分光光度法分析。本文攷察和分析瞭配位數、pH值、浮選時間對雙水相氣浮浮選的影響,得齣浮選最佳條件:pH值9.5,浮選時間為6 min,n(Ca2+):n(Tc)=1∶1。

The experiment for determining content of tetracycline is made by aqueous two - phase gas floatation,the author elect the n -propyl alcohol for organic solvent and sodium chloride for separating phase reagent, sodium hydroxide (nmriatic acid) adjust pH. The hydrophobic complex composed of Ca (Ⅱ ) and TC is floated into organic phase, the data is obtained by spectrophotometry after floatation. This paper study and analysis on influence of the coordination number, pH values and floatation time, the most optimal conditions : pH = 9.5, the floatation time is 6 minutes, n ( Ca^2 + )/n (TC) = 1 : 1.
