Abstract: Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.

Abstract: The invention relates to a system and a method for treating waste water using a passive phosphorus-capture filter lined with wood activated by the impregnation of a metal in the form of hydroxide, more specifically aluminum hydroxide or iron hydroxide. This system demonstrates phosphorus removal performances which are very closely linked to the release of iron and which support the observation that iron releases follow a cyclical trend. The method according to the invention also clearly demonstrates the cyclical nature of the reduction of phosphorus, directly linked to the same cycle of iron release at the outlet. When the medium is aerobic, it can precipitate the released iron in the form of hydroxide and thereby limit the release of iron into the outflow water and consequently its residual phosphorus. This model thus allows the service life of the system to be extended, while simultaneously taking advantage of the precipitation/solubilisation cycle of the iron observed in the medium under reducing conditions.

In the desulfurizer prepared by this method, the initial balls constitutes 0.98 wt %-9.03 wt % of the desulfurizer, the non-crystalline iron oxide hydroxide constitutes 90.29 wt %-98.62 wt % of the desulfurizer, and the organic binder constitutes 0.58 wt %-0.89 wt % of the desulfurizer. The present invention solves the problems that the desulfurizer with high sulfur capacity in the prior art has a high binder content and poor water resistance and diffusion performance, and provides a process for preparing a desulfurizer with high sulfur capacity, wherein a desulfurizer with high sulfur capacity and low binder content, good water resistance, good diffusion performance can be prepared.

Abstract: The invention discloses a micron-grade magnetic core coated ferrocyanide adsorbent for removing Cs ions in radioactive wastewater and a preparation method thereof. The adsorbent takes magnetic Fe3O4 as a core, the surface is coated with a dense SiO2 single layer serving as a protective layer, and an active component is metal ion stabilized potassium ferrocyanide coated on the outer layer, wherein stabilized metal ions comprise Ti, Zn, Cu, Ni, Co, and Zr. The particle size of the adsorbent is 0.2-5 μm, the adsorbent in the outermost layer is conductive to improving the adsorption efficiency for Cs+ ions, and an external magnetic field is adopted for realizing solid-liquid phase separation. The preparation method comprises the following steps: coating a hydrated metal oxide of Ti, Zr or Co, Ni, Cu or Zn on the surface of Fe3O4SiO2 to form a composite magnetic material, wherein the hydrated oxide performs hydroxyl polymerization reaction with the surface of SiO2 to produce M—O—Si bonds to improve the bonding strength between M and the surface of SiO2; and finally reacting the composite magnetic material with a potassium ferrocyanide solution to form the required composite adsorbent, wherein the metal ions M achieve the effects of stabilizing the ferrocyanide and also achieve a bridge effect for bonding the ferrocyanide and the composite magnetic material together.

The carbon coated silica particles can be useful in a wide variety of applications including, for example, for use as sorbents in chromatography.
