摘要: For the development of decentralized treatment systems for road runoff, determination pollutant removal capacities is essential. The aim this study was to evaluate impact boundary conditions on simultaneous copper, nickel, and zinc by six sorbents used urban stormwater (i.e., granular activated alumina, anthracite, reactivated carbon, ferric hydroxide, calcium carbonate, lignite). batch experiments, were determined at initial concentrations within range 2.5–180 mg/L with a rotary shaker. Further influences investigated: use horizontal shaker up 1080 mg/L, variation pH value (5 7), presence buffer. Furthermore, filtration process studied. Kinetic experiments conducted contact times between 5 min 120 min. Lab-scale column inflow 2.5 (copper nickel) 5.0 (zinc) an time 11 performed comparison. Selected subsequently carried out changes in time. One result that it essential conduct metals interest. deviated from experiments. Batch under well-defined can be different production batches. Column give more faithful capacity considering realistic should preferred determine efficiencies service lives.
