摘要或動機

We are conducting research for the purpose of treating contaminated water generated by the nuclear accident with C.moliniferum. In previous research, the school seniors examined whether there is a difference in absorption by changing the wavelength of the LED to establish efficient Sr2+ absorption conditions. As a result, the red wavelength was found to be effective for the efficient Sr2+ absorption of C. moniliferum. Therefore, in this study, in order to verify how much Sr is actually absorbed into the cell, the amount of Sr absorption using an atomic absorption photometer is quantified, and the previous research has shown that red is effective for the efficient Sr2+ absorption. The wavelength was considered to be effective because of photosynthesis, and was observed with a scanning electron microscope (SEM) using the photosynthesis inhibitor (DCMU). As a result, it was clarified that C. moniliferum absorbs Sr intracellularly, and photosynthesis was related to absorption.
