Do a novel process utilizing mechanochemical sulfidization to remove lead from cathode ray tube funnel glass?
In this research, a mechanochemical sulfidization method was proposed to recover lead from waste cathode ray tube (CRT) funnel glass. CRT funnel glass was co-ground with sulfur in N2 atmosphere by mechanical milling. After milling, lead in CRT funnel glass was transferred into lead sulfide (PbS). Using this process, current nfiineral processing technology, such as flotation separation, might be used to recover PbS from the ground sample. The process can be applied to treat other leaded glass or lead-containing wastes.
High level of TAFI antigen in attack-free period of FMF disease shows ongoing subclinical inflammation and hypercoagulability. Clinicians should be careful about thrombosis even in patients at clinical remission. Also, genetic tests must be considered to predict clinical outcome and to reduce complications of FMF disease.
