The waste polymer activated carbon was prepared from tyre by NaOH activation, which was used for the adsorption of dye Direct Scarlet 4BS in aqueous solution. The influences of pH value, activated carbon dosage, adsorption time and reaction temperature on adsorption rate were discussed in details. It was shown that the activated carbon dosage, adsorption time and reaction temperature had an important effect on the removal of dye Direct Scarlet 4BS in aqueous solution. However, the removal of dye Direct Scarlet 4BS was little dependent on pH value in solution. At 0.6g of activated carbon, 60mg/L of initial dye concentration, 60min, 35°C and pH 4.0, the removal of dye Direct Scarlet 4BS reached 85.14%.Keywords

Nitrogen (N) is an essential element for living organisms in aquatic ecosystem. However, excess nitrate in this ecosystem could degrade water quality due to eutrophication. Ammonia is usually found in aqueous environments. It affects fish and other aquatic life and recreational use of water. In this study, the acidic ion exchange resins were chosen as adsorbent to adsorb the high concentration of ammonia from wastewater. The experimental results showed that reaction of temperature, the amount of the ion exchange resins and reaction time had an important influence on the removal rate of high concentration of ammonia from wastewater. The experimental data correlated well with the Langmuir adsorption isotherm. It was also suggested that the adsorption process was homogeneous adsorption. The ammonia from aqueous solution adsorption on the acidic ion exchange resins was a monolayer adsorption.
