title: [Algaecidal effect of a nanomaterial sheet].
abstract: A nanomaterial algaecidal sheet was prepared for algaecidal treatment. The results of algaecidal activity of the nanomaterial algaecidal sheet in lab and field experiments were investigated. It was showed that under the ratio of the area of nanomaterial algaecidal sheet to the volume of algal cell suspension at 0.08 cm2 x mL(-1) and light intensity at 3000 1x, the cell density of algal cell suspension of Microcystis aeruginosa, Anabaena 7120, Euglena gracilis, and Chlamydomonas reinhardtii decreased by 77%, 69.1%, 89.1% and 56.9% respectively after 24 h treatment, and Chla concentration of algal cell suspension of Navicula incerta decreased by 18.7%. Chla concentration of a site with algal bloom in Wuli Lake decreased by 76% after 1 day treatment in the field experiment. Acute fish toxicity test (5 days) of the nanomaterial algaecidal sheet showed no significant toxicity.
