Abstract Cyanide is one of the toxic materials in environment and included as a hazardous waste. One agro-industrial wastewater containing cyanide from tapioca industry. Various methods, including constructed wetlands, can reduce compounds wastewater. Some plants used wetlands technology include Pistia stratiotes C. zizanioides , L. This study aimed to analyse effect L media height on reduction...

This work studied the effect of nitrogen functional group modification on activated carbon synthesized from vetiver root waste pores development. Synthesis was carried out by hydrothermal carbonization at a temperature 225 ⁰C for 18 hours followed chemical activation using K2FeO4as agent in furnace 800 2 with atmosphere flowed rate 100 mL/minute. Urea used as source. The variation urea concentr...
