Efficient uptake of lead (II) ions using biocompatible chitosan nanoparticles and studying effective parameters on removal efficiency

Low-cost and biocompatible chitosan natural polymers downsized successfully by means of a chemical procedure The surface properties and size of chitosan nanoparticles (CNP) were characterized using a Scanning Electron Microscope (SEM). CNPs were utilized for separation of lead (II) metal ions from aqueous solution, and the influence of effective factors such as lead initial concentration and pH value were investigated
