藻体海水培养液中铜的化学存在形式

CHEMICAL SPECIES OF COPPER IN ALGAE CULTURAL SOLUTION OF SEA WATER

采用金属络合物通式模型,在IBM-PC计算机上计算了不同pH(7.5～9.5)、碱度(2.3～2.5mmol dm^(-3))和加入不同浓度的铜离子(1.0×10^(-4)～1.0mg dm^(-3))条件下,海水培养液中铜的主要化学存在形式分配的百分数。还给出了计算机程序框图和主要化学存在形式含量的百分数随pH、碱度和铜浓度变化图。

The contents of main chemical species of Cu in algae cultural solution of sea water with different conditions of pH ( 7. 50-9. 50) , Cu concentration (1.0×10-4 - 1.0mg/dm3) and alkalinity (2. 3-2. 5mmol/dm3) were calculated with the metal complex common model, using a IBM-PC micro-computer.The computer flow chart and the figures that the percentage of the main species Changs with different pH ALK and concentration of Cu were given.
