中文摘要 | The aim of this paper is to study the adsorption of copper ion and chlorine residual from tap water by chitosan, which was prepared from crab shell waste. Both static and dynamic experimental methods were used. The concentrations of copper ion and chlorine residual in water were measured by AA and spectrophotometer, respectively. It was found that most of the copper ion and chlorine residuals in tap water were adsorbed by chitosan. Consquently, chitosan can be employed as adsorbent to improve the quality of drinking water. |
英文摘要 | 由於飲用水水源常含有金屬離子或有機質,而自來水公司又常加氯消毒,致水中 常有殘餘氯離子,這些化學物質均會影響飲用水品質。本研究目標即利用蟹殼廢棄物所研製 之幾丁聚胺醣(Chitosan),吸附水中之氯離子及銅離子。實驗方法包括靜態振盪吸附及動 態吸附,並分別應用原子吸收光譜儀(AA)與分光光度計測量水中銅離子及殘餘之氯離子。 經由實驗結果發現幾丁聚胺醣對於氯離子確具有不錯的吸附能力,足以改善飲用水之品質。 |
