中文摘要 | 本研究比較了目前常用的數種水質分析方法-傳統法,FIA法、簡易儀器比 色法、套組比色法及簡易試紙比色法等.測定養殖水中氮-氮及亞硝酸-氨準確性。吾人將 含氨-氮0.09-7.92mg/l等的20個淡水水樣以傳統法、FIA法、簡易儀器比色法及套組比色 法分析,結果顯示,FIA法及簡易屬器比色法之測出值分別較傳統法者乎均偏高約3.7%及 85%,套組比色法則偏低約5.25%。簡易試紙比色法其低濃度組(0.16∼5.4 mg/l)以0.3 ∼21.0mg/l等20個水樣進行測試,結果發現其測出值較簡易儀器比色法者乎均偏高約23.2 %,高濃度組(15.5∼140.0mg/l)以41.0∼130.0 mg/l等6個水樣測試,其值則乎均偏低 約15.6%。海水方面,採取海水水樣21個,其氨、氮的含量以傳統法測定為0.02∼ 6.03mg/l,以FIA法、簡易儀器比色法及套組比色法的測試結果均低於傳統法者,其平均誤 差分別為8.8%、10.0%、及14.8%。套組比色法的測試結果較佳於應用在淡水水樣的測 定。而亞硝酸-氮的測定方面,將82.5∼641.5 μ g/l等的23個水樣以傳統法、FIA法、簡 易儀器比色法及套組比色法進行測試,結果發現,FIA法之測出價平均高出傳統法者約10.1 %,簡易儀器比色法的測出值平均高出傳統法者約1.3%,而套組比色法則平均偏低約29.2 %。將0.29∼7.80mg/l等的19個水樣以簡易試紙比色法分析,結果顯示其測出值較簡易儀器 比色法者乎均偏低約25.4%。海水亞硝酸-氮的比較方面,採取海水水樣24個,其亞硝酸- 氨以傳統法測定為2.0∼2647.2 μg/l,以FIA法及簡易儀器比色法測試結果的誤差乎均 分別偏低0.5%及4.4%,而套組比色法則乎均偏低約34.4%。此外.本研究亦曾就簡易儀 器比色法、套組比色法及簡易試紙比色法等,比較其測定氨-氮及亞硝酸-氮的標準液之準 確性,結果顯示其誤差大都小於應用在水樣的測定。 |
英文摘要 | Using the traditional method, FIA (Flow injection analysis), simple-instrument (Spectroquant), kit (Microquant) and simple-test-strip (Reflectoquant), the ammonia-N (un-ionized plus ionized ammonia as nitrogen) and nitrite-N (nitrite as nitrogen) in aquaculture system were investigated. Twenty fresh water samples (0.09~7.92mg/l of ammonia-N) were tested for the ammonia-N. The deviations of FIA, Spectroquant and Microquant in comparison with the traditional method were 3.7%, 8.5% and 52.5%, respectively. The underestimation (52.5%) of Microquant must be taken notice by the users. In the Reflcetoquant method, the low concentration group was tested with 20 samples (0.3~21.0mg/l of ammonia-N). The result was by 23.2% higher than the traditional method. The result of high concentration group was by 15.6% lower than traditional method. The result of high concentration group was by 15.6% lower than the traditional method, as it was tested with 6 samples (41.0~130.0mg/l of ammonia-N). There were 21 sea water samples, and their concentration of ammonia-N was 0.02~6.03mg/l. The deviations of FIA, Spectroquant and Microquant methods was 8.8%, 10.0% and 14.8%, respectively. The nitrite-N in the 23 samples (their concentrations were between 82.5~641.5μ g/l)were determined by a traditional method, FIA, Spectroquant and Microquant. The result of FIA and Spectroquant was higher than that of traditional method by 10.1% and 1.3%. On the contrary, Microquant was much lower by 129.2% of which the users should take notice. The Reflectoquant was tested in 19 samples (0.29~7.80mg/l of nitrite-N), and the result was by 25.4% lower than traditional method. Based on the nitrite-N test of sea water samples, the concentration of nitrite-N in 24 samples was 2.0~2647.2μg/l by the traditional method, the deviation of FIA and Spectroquant was 0.5% and 4.4%, respectively. The result of Microquant was by 34.4% lower than that of traditional method. In this study, the checking results of Spectroquant, Microquant and Reflectoquant for standard solutions of ammonia-N and nitrite-N were also investigated, the deviations of these three methods were lower than water samples'test. |
