“…Joseph Hanak introduced the combinatorial approach in the 1970s as a way to prepare and screen numerous materials simultaneously. − The approach enabled the quick determination of a correlation between an observed material property and the material composition and allowed the faster discovery of new materials. Combinatorial materials science (combi) methods were found suitable for the development of impregnated activated carbon (IAC) adsorbent materials for respiratory filters. − Parallel preparation and subsequent testing of many compositions of impregnated activated carbon was achieved and a correlation can be made on the observed diffraction patterns and the gas adsorption performance of the material. − …”

Impregnated activated carbons (IAC) are widely used materials for the removal of toxic gases in personal respiratory protection applications. The combinatorial method has been employed to prepare IACs containing different types of metal oxides in various proportions and evaluate their adsorption performance for low molecular weight gases, such as SO(2) and NH(3), under dry conditions. Among the metal oxides used for the study, Mn(3)O(4) was found to have the highest capacity for retaining SO(2) gas under dry conditions. NiO and ZnO were found to have similar NH(3) adsorption capacities which are higher than the NH(3) capacities observed for the other metal oxide impregnants used in the study. Although Cu- or Zn-based impregnants and their combinations have been extensively studied and used as gas adsorbents, neither Mn(3)O(4) nor NiO have been incorporated in the formulations used. In this study, ternary libraries of IACs with various combinations of CuO/ZnO/Mn(3)O(4) and CuO/ZnO/NiO were studied and evaluated for their adsorption of SO(2) and NH(3) gases. Combinations of CuO, ZnO, and Mn(3)O(4) were found to have the potential to be multigas adsorbents compared to formulations that contain NiO.

Abstract. Carbonized waste cotton were prepared by activate solution carbonization method. The effects of moisture content, carbonization time and carbonization temperature on the yield of carbonization were investigated. At the same time, the adsorption property of direct dye of the carbonized cotton products was studied. Results show that carbonization yield increased first and then decreased with the increasing of the moisture content using pure water as the activate solution at the same other conditions; Carbonization yield decreased as the extension of carbonization temperature and carbonization time. Carbonization yield and adsorption of direct dye increased when using phosphoric acid solution as the activate solution. Adsorption of direct dye increased with the increasing of phosphoric acid concentration.

The increasing water demand and the worldwide shortage of clean water call for new technologies for wastewater treatment, of which sorption is recognized as simplest and efficient method for all major water pollutants, including heavy metal ions, organic dyes and organic solvents. In this context, graphene, an atomically thin two-dimensional hexagonal arrays of carbon atoms, and its analogs have been visualized as ultimate materials for the separation of pollutants from water due to properties such as superhydrophobicity, superoleophilicity, chemical-environmental-thermal stability, chemical manipulability, controllable morphology, texture, porosity and accessible surface area, facile processing, low density, biocompatibility and low-cost synthesis from a variety of abundant carbonaceous precursors. This chapter begins with an introduction of water purification, related processes and fundamentals of adsorption and absorption phenomenon. The next section emphasizes the importance and advantages of graphene as sorbent, brief about its synthesis, types of graphene-based composites/hybrid systems and their synthesis strategies. The last section throws light on the performance of graphene-based foams, aerogels and composites/hybrids for the separation of metal ions, organic dyes and various oils/organic solvents, supported by comprehensive literature account. Finally, the chapter concludes with the comments on the current status, major challenges and future scope in the direction.
