The rational utilization of solid waste has always been a worldwide concern. In this study, coal fly ash (CFA) and red mud (RM) were used in combination to synthesize efficient heavy metal adsorbents. A new way resource recycling was provided with the collaborative reuse CFA RM. To obtain modified composite materials, RM mixed melted three ratios. After modification, these materials then utilized adsorb Pb, Cu, Cd water both single ternary systems. physicochemical properties CFA, RM,...
The huge annual output of coal fly ash is harmful to the environment, but it widely used because its good adsorption potential. In this study, using as a raw material and sodium hydroxide an activator, novel adsorbent was synthesized at 300 °C adsorb low concentrations ammonia nitrogen from water. scanning electron microscopy, X-ray diffraction analysis, Fourier transform infrared spectroscopy, energy dispersive surface area porosity analyzer were analyze adsorbent’s physicochemical...
The identification of clay minerals is an essential step in soil research. However, many traditional methods have the limitations tedious steps, slow speed, complicated pre-processing and poor discrimination. A novel scheme for rapid accurate soils was proposed based on chemical composition structure information kaolinite, talc, illite, vermiculite, montmorillonite, chlorite sepiolite obtained by combining different optical analysis methods. In this scheme, index alteration values first...
