Result comparison of heavy mineral separation with different specific densities of bromoform;

Based on the summary of other approaches for conodont separation, this paper mainly introduces the experimental devices, procedure and major points of using heavy-liquid made up of bromoform and acetone to separate conodonts as well as the method to recycle heavy-liquid.

7 halogenated hydrocarbons in adhesives were determined with bromoform as internal standard by gas chromatography coupled with micro-electron capture detector(GC/ECD) after ethyl acetate ultrasonic extraction and filtration.

Study on flame-resistant and mechanical performance of modified natural rubber latex by trichlorobromomethane;

Influence of technological condition on trichlorobromomethane modified natural rubber latex;

The results showed that nano SiO_2 and nano CaCO_3 for trichlorobromomethane modified natural rubber latex have some reinforcing action with the increase of usage of reinforing agent,the upward trend of performance onto mechanics showed,when consumption of agent reached a certain degree,with the increase effect of reinforcing agent usage,the reinforcing effect had deterioration.
