Mechanical and morphological characteristic investigations of deinked used newsprint paper via ultra-sonochemistry method
Printed newspaper is one of the print-based media published daily in large quantities. The focus of this research is to remove the ink from used newsprint with alkaline treatment by using ultrasound sonochemistry method. Newsprint sheets collected were characterized by mechanical and morphology test...
