experimental study of nitrate absorption isotherms determination on latium composite overactive carbon

the aim of this study is to verify the amount of nitrate absorption on latium composite over active carbon in which ph parameters, temperature, pollutant concentration, contact time for absorbent were considered. it was determined that optimum condition for absorbent are ph=3, t= 0 ˚c and initial concentration of solution=10 ppm, then absorption parameters verified and after drawing absorption isotherms (langmuir, freundlich) in nitrate absorption process it was evident that languir model had the most conformity with experimental data gained latium composite on active carbon.
