نوع فایل :PDF تعداد صفحات :13 سال انتشار :1395 چکیده Background and Objective: environmental pollution by hazardous toxic metals is one important environmental issue, nowadays. Extensive use of heavy metals in the industry has increased concentrations of these metals higher than background values in water, wastewater, air and soil. These heavy elements and compounds have irreparable impacts on the environment and human. The present study aimed to remove or reduce heavy metals of lead, zinc and cadmium from aquatic solutions by carbon nanotubes modified with chitosan.Materials and Methods: In this study, multi-walled carbon nanotubes modified with chitosan were used as absorbent. Heavy metal nitrate salt in distilled water was used as sample. Following...
