中文摘要 | 水樣色度分析技術,傳統上以鉑鈷法(APHA)為主。近來由於儀器發展快速,以 ADMI,Lovibond等方法分析色度之技術逐漸被引用,過去對於中高色度之色度偵測技術已 發展十分完整,對於屬於飲用水低色度範圍之分析技術較少被提及。 本路究即針對此一低色度範圍水樣,以標準鉑鈷方法配製樣品,以三種ADMI及Lovibond 方法進行探討。結果顯示以5cm cell所獲得ADMI2及ADMI3較具有代表性,而APHA與Lovibond 亦是1:0.1之比例關係。pH值對色度偵測影響很大,且此一現象經證明為不可逆反應。 |
英文摘要 | Color measurement technique is traditionally being used by p1--Co standard method suggested by APHA. Due to rapid development of instrument, several new automatic color measurement techniques including: ADMI and Lovibond method have been proposed recently. For samples with medium to high color units the analytical methods have been well-developed; while for tap water samples containing low color unit, the analytical technique is still under developing. In this study the synthetic Pt-Co standard solution was prepared and its color unit was measured by 3 types of ADMI unit and Lovibond method. From result revealed, with 5 cm cell length, ADMI2 and ADMI3 provided satisfactory results. APHA and Lovibond has a 1 to 0.1 ratio. The pH value caused an irreversal reaction and had a significant effect on color measurement. |
