| 中文摘要 | 本文乃以2X10-3N硼酸碘液與聚乙烯醇的反應呈色,當聚乙烯醇含量在1 g/1以下時,以紫外光度計掃瞄,在波長480.5nm,可得標準檢量線。對含其它漿料之廢水,加1% HCI加熱處理法,進行波長480.5nm在聚乙烯醇含量0.6%以下時可得。若比色前將pH值調回中性,則所得值較接近正確值。 |
| 英文摘要 | At the wave length 480.5nm of visible-range spectro-photometer, it is necessary to establish the quantative standard curve on the Polyvinyl Alco-hol waste water with boric acid-iodine solution. When the concentration of Polyvinyl Alcohol is below 1g/1 (Concentration = 4.0492 Absorance-0.1051). As the concentration of Polyvinyl Alcohol below 0.6 g/1 of the de sizing waste water was mixed with Polyvinyl Alcohol and starch, in order to remove the interference from starch we can add 1 % HCI solution and heat. The more accurate result by adjustment the pH value of sample to perhaps 7 was obtained. |
