Innovative methods for electronic waste recycling and development of some chemical sensors for the assessment of the constituents of these wastes
Mahmoud Abdelwahab Fathy Sayed;
Abstract
Summary
- The thesis content can be portrayed briefly as five chapters:
➢ Chapter (I): General introduction:
• Chapter (II): Lead Extraction from Spent Cathode Ray Tube by
Mechanochemical Activation:
A mechanochemical activation technique to effectively extract lead
from funnel glass of cathode ray tube (CRT) is proposed. More than
85.7% of lead can be extracted from the funnel glass powder in 5 M
sodium hydroxide solution at 80°C after mechanochemical activation by
ball milling with Ethylenediaminetetraacetic acid (EDTA). The chemical
breakage in the glass inner structures will ease leaching of the activated
Pb glass. The effects of time and temperature on the lead dissolution were
investigated and a model was developed to depict the kinetic relationship.
➢ Chapter (III): Potentiometric study for Selective Determination of
Thiocyanate in the Saliva and Urine of Cigarette Smokers using
solid type PVC membrane sensor: ➢ Chapter (IV): Paper Strip and Ceramic Platform Based
Potentiometric Sensors with Polyaniline Solid Contact for
Continuous Monitoring of Chromium in Industrial Samples: ➢ Chapter (V): Gold plate electrodes functionalized by multiwall
carbon nanotubes film for potentiometric thallium (I)
detection:
