ABSTRACT: Silver nanoparticles (AgNPs) are becoming an
emerging pollutant of the environment. In this study, the efficacy of
Multiwalled carbon nanotubes (MWCNTS) to remove AgNPs from aqueous solution at
a concentration of 250 and 500 mg/100 ml MWCNTS was investigated. The results
showed that the adsorption of AgNPs by 250 and 500 mg/100 ml MWCNTS after a
contact time of 10 min., 30 min., 60 min., 120 min. and 240 min was 33.95%,
34.36%, 40.32%, 45.33%, 58.53% and 57.29%, 61.27%, 64.89%, 87.21%, 88.58%, respectively.
The statistical analysis of data showed that, after adding 250 and 500 mg/100 ml
MWCNTS, the total residues of AgNPs were significantly reduced in all MWCNTS
exposed samples when compared to the control groups (P
