Abstract

. Scenedesmus sp. is a freshwater green alga that functions as an ionic biosorbent and can also be a bioindicator for water contaminated with hexavalent chromium Cr(VI) ion. This study aimed to observe the growth of Scenedesmus sp. exposed to Cr(VI) ion at various concentrations and analyze the remaining Cr(VI) ion that did not undergo biosorption by microalgae. This research was conducted on Scenedesmus sp. microalgae growth media using five bioreactors, each with a different Cr(VI) ion exposure concentration. The remaining ion in the growth media was analyzed for its concentration with an ultraviolet-visible spectrophotometer at time variations with an interval of two days. Maximum biosorption with exposure to Cr(VI) occurred at a concentration of 1.0 ppm on day 12 of 99.93%. At concentrations of 5.0 ppm and 7.0 ppm, microalgae growth was very poor, indicating the medium was toxic.

微藻对六价铬Cr(VI)的生物吸附研究

． Scenedesmus sp.是一种淡水绿藻，具有离子生物吸附剂的功能，也可以作为六价铬(Cr(VI))离子污染水的生物指示剂。本研究旨在观察不同浓度Cr(VI)离子对Scenedesmus sp.生长的影响，并分析未被微藻生物吸附的剩余Cr(VI)离子。本研究在Scenedesmus sp.微藻生长培养基上采用5个不同Cr(VI)离子暴露浓度的生物反应器进行。用紫外-可见分光光度计测定生长介质中剩余离子的浓度，时间间隔为2天。暴露于浓度为1.0 ppm的Cr(VI)时，第12天的生物吸收率达到99.93%。在5.0 ppm和7.0 ppm浓度下，微藻生长非常差，说明培养基有毒。
