ESTIMATION OF VIOFORM IN 

 GAUZES. 



E. j. von Itallie had occasion to ex- 

 amine a number of samples of gauzes 

 and cottons for their A'ioform (iod- 

 chlor-oxy-quinolin) content. He states 

 that he found in literature bearing on 

 this subject only two methods which with ten times its volume of water, 

 could be employed. Both of these phenolphthalein solution is added and 

 methods were subjected to a critical ex- then nitric acid until all color disap- 

 amination by ( LJtz iMiar. Zentralh. 49 pears. The vioform which is thus pre- 

 (1908), 383), and both were reported cipitated is collected on a filter, washed 

 as faulty. Utz reports th'at in one ^vith water and dried over sulphuric 



traction apparatus and extracted during 

 a period of two hours l>y means of half- 

 normal alcoholic potassium hydroxide. 

 The apparatus is then filled with alco- 

 hol and the extraction continued for 

 two further hours. 



The extract thus obtained is diluted 



of these methods the gau/.c or cotton 

 is ashed, a jjrocess which causes a vola- 

 tilization of at least lo^o of the chlo- 

 rides. V. Itallie has recommended the 

 following method and states that it 

 yields good results. From two to five 

 grammes of the gauze or cotton to be 

 examined arc i)laced in a Soxhlet ex- 



acid. For the complete fixing of its 

 halogens vioform requires 70.66% of its 

 weight in silver.
