The capability of nanoparliclcs to remove NH4~ from contaminatedAmmonium removal from aqueous solution by silver nano particles
solution was then studied. Parameters like types of AgNPs. pH of ammonium solution, contact lime, adsorbent dosage and initial ammonium concentration THAI NGUYEN UNIVERSITYUNIVERSITY OF AGRICULTURE AND FORESTRY%VU TRA GIANG1970Ỉ20AMMONIUM REMOVAL FROM AQUEOUS SOLUTION BYSILVER NANO PARTICLESBACHELOR Ammonium removal from aqueous solution by silver nano particles 5 to 60 and decreased in initial concentration of NH4". The most appropriate conditions for Ammonium adsorption onto AgNPs in batch experiments obtained at pH 9. contact time of 60 min. 1.824 mg AgNPs/25 mL of Ammonium solution with initial concentration of 5 mg/ L. At this condition, the highest a Ammonium removal from aqueous solution by silver nano particlesdsorption capacity of Ammonium onto AgNPs reached 100.48 mg.g. Isotherm adsorption was also described by the Langmuir model with a constant correlatioAmmonium removal from aqueous solution by silver nano particles
n (R2) is 0.9339. . With highest R; (0.885), the adsorption kinetic of Ammonium onto AgNPs obeyed Elovich model with the chemical sorption process.KeyTHAI NGUYEN UNIVERSITYUNIVERSITY OF AGRICULTURE AND FORESTRY%VU TRA GIANG1970Ỉ20AMMONIUM REMOVAL FROM AQUEOUS SOLUTION BYSILVER NANO PARTICLESBACHELOR Ammonium removal from aqueous solution by silver nano particleso Dr. Van Huu Tap who in spile of being extraordinarily busy with his duties, took lime out to hear, guide, keep me on the correct path and complete report during the lime of eondueling the research, which also helped me know about so many new things I am really thankful to him.I would also like to Ammonium removal from aqueous solution by silver nano particlesexpress my great appreciation to Dr. Vu Xu an Iloa for his constant support, patient guidance and suggestions related to my work.THAI NGUYEN UNIVERSITYUNIVERSITY OF AGRICULTURE AND FORESTRY%VU TRA GIANG1970Ỉ20AMMONIUM REMOVAL FROM AQUEOUS SOLUTION BYSILVER NANO PARTICLESBACHELORTHAI NGUYEN UNIVERSITYUNIVERSITY OF AGRICULTURE AND FORESTRY%VU TRA GIANG1970Ỉ20AMMONIUM REMOVAL FROM AQUEOUS SOLUTION BYSILVER NANO PARTICLESBACHELORGọi ngay
