摘要: 采用分光光度法测定浮游植物中叶绿素a的含量,研究光照和温度对提取浮游植物叶绿素a的影响,以确定提取浮游植物叶绿素a的最佳条件。在抽滤过程中严格避光,并用冰水混合物冷却至0 ℃保存,抽滤水样。浸提分为避光(低于200 lx)冷藏(-1~1 ℃)组、光照(1 100~1 700 lx)冷藏(-1~1 ℃)组、避光(低于200 lx)常温(26~30 ℃)组和光照(1 100~1 700 lx)常温(26~30 ℃)组,每组放入10 mL丙酮溶液(90%)浸提19 h。4组平均提取量分别为:避光冷藏组155.73 μg/L;光照冷藏组136.24 μg/L;避光常温组116.67 μg/L;光照常温组89.85 μg/L。结果表明浮游植物叶绿素a的最佳提取条件为冷藏、避光。

Abstract: The spectrophotometric method in different conditions of light and temperature, extraction of phytoplankton chlorophyll a determined, to study the different illumination and temperature on the extraction of phytoplankton chlorophyll a and determine phytoplankton chlorophyll a in the optimum conditions of extraction. Strictly avoid light in the filtration process, and use the ice water mixture is cooled to 0 ℃ preservation, water filtration. Leaching provided to avoid light(less than 200 lx refrigerated(-1-1 ℃)group, light(1 100-1 700 lx)cold(-1-1 ℃)group, evades the light(less than 200 lx)at room temperature(26-30 ℃)group and light(1 100-1 700 lx)at room temperature(26-30 ℃)group, each group into the 90% acetone solution extraction 19 h. The average extraction amounts of the four groups were as follows: 155.73 μg/L of the cold storage group and 136.24 μg/L in the light cold storage group, 116.67 μg/L in the ambient temperature group and 89.85 μg/L in the normal temperature group. The results showed that the optimal extraction conditions of phytoplankton chlorophyll a were cold storage and light avoidance.

Key words: chlorophyll a, extraction, temperature, illumination
