The process of ,palladium(II) chloride complex ion adsorption on activated carbon, was investigated. The influence of variable parameters such as the initial concentration of the Pd(II) complex (from 0.04 to 2.25 mmol·kg–1) and temperature (from 294 to 348 K) was determined. Experiments were conducted in the solution with pH equal to 0 and 1. It was found that the Freundlich adsorption ...

Introduction. Low strength municipal ,wastewater, is characterized by its low organic content (COD < 500 mg/L) and high solids content (TSS < 250 mg/L) (Henze et al., 2008).The most widely used technology for ,wastewater, treatment is based on the activated sludge process, but this implies a high cost for aeration as well as the generation of high amounts of biomass (sludge) that needs to be ...

29/4/2016, · No ammonium ,stripping, was measured in cultures in the absence of light for all tested temperatures (results presented in Fig. 6 for 25 °C; ,data, are not shown for 5 °C and 15 °C). Under these conditions, no microalgal growth was observed and consequently the pH remained constant at around 8.5 (,data, not shown).
