Methods employing \(N, N\)-diethyl-p-phenylenediamine are described for estimating the concentrations of chlorine dioxide, free available chlorine, and free available bromine in mixtures containing all three components or any combination of two components. In threecomponent systems chlorine and brom

The inorganic constituents of low-rank Victorian brown coal, which are mainly present as inherent inorganic combinations attached to the coal molecule, are different from the minerals present in higher-rank coals. Changes in the state of combination of the inorganics in the chars of these coals have
Utilization of coal mine saline waters is regarded as the most appropriate method of solving the ecological problems created by these waters in Poland. One of the methods of utilizing the most concentrated saline waters --called coal mine brines, which is presently being considered --consists in usi
Samples of a high-volatile bituminous coal were chlorinated with Cl, in various media. Two chlorination procedures were used: dry and wet chlorination. The wet method led to decreases in high and low temperature ash yields, while no significant changes in yield took place with the dry chlorination
