Improvement Of Total Sulphur Measurement Techniques For Management Of Reactive Mine Tailings, Adnan Hossain Khan

Electronic Thesis and Dissertation Repository

A sample preparation method for total sulphur measurement in reactive mine tailings was developed by ultrasound assisted digestion (USAD) and inductively coupled plasma-optical emission spectroscopy (ICP-OES) technique. KZK-1, asericite schist, was selected as the certified reference material (CRM) and Musselwhite gold mine tailings were used as tailings sample. Experimental factors (i.e. digestion time, temperature and acid-oxidant combination) were studied in two steps. In the first step, a two-level and three-factor (2³) full factorial design of experiment was applied and the total sulphur was measured by USAD and ICP-OES technique. The best result at 95% confidence level (P …
