Resumo: | This study aimed to quantify the amount of free residual chlorine present in the samples and to evaluate which doses comply with the Consolidation Ordinance. To carry out the study, we used cyanobacterium Cylindrospermopsis raciborskii, recurrent in flowering in Brazilian springs. Chlorine gas was the oxidation selected due to its low-cost and easy handling. Analyses were performed at 1,0 x 104 and 1,0 x 106 cells.mL-1 and at 30 min and 24 h contact times. The results showed high chlorine consumption and, consequently, low concentration of free residual chlorine. |
