Sažetak
The use of natural remediation methods to remove contaminants from wastewater is becoming more popular. This study specifically attempted to determine the viability for using wetland plant Spirodela polyrhiza (Lemnaceae) to remediate water contaminated with sodium dodecylbenzenesulfonate (SDBS). The studied species is aquatic plant widespread throughout the world in a wide variety of water bodies and faces no major threats. The study was carried out at the level of laboratory-scale constructed wetland containing mature plants of Spirodela polyrhiza. Plants grown in an aquaria for experimental purposes were exposed to 5 mg/L concentration of SDBS. The experiments were performed in the absence of nutrients. Two different controls were carried out in parallel: plants in a SDBS free medium and medium containing SDBS, but free of plants. The aqueous culture media was sampled (15 mL) every 24 h for SDBS analysis. In order to determine the amount of anion surfactant, MBAS method employing UV/Vis spectrophotometer Shimatzu in 652 nm wavelengthwas used. The test kit LCK 414 for Chemical Oxygen Demand (COD) measurements was used for monitoring of water quality. The amount of chlorophyll and carotenoids in plant leaves was measured spectrophotometrically in order to estimate stress level in plants. This study demonstrated that Spirodela polyrhiza could be considered as appropriate plant species for potential application in phytoremediation.
