A composition and method for sorbing a mobilized metal which can optionally include uranium, and which can optionally be used for capping uranium-containing mining tailings. The method can include forming a layered structure atop the metal-containing mining tailings which sorbs the metal and prevents it from being discharged as surface water runoff and which prevents it from being released into groundwater.

The present invention relates to a neutralizing absorbent for decontaminating a leaked chemical substance, a method of preparing the same, and a neutralizer filled with the same. The neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention includes an inorganic adsorbent, which is commonly usable in neutralizing absorption of acidic, basic, and/or organic chemical substances, at 40 to 60 wt %, a thickener at 20 to 30 wt %, a surfactant at 20 to 30 wt %, and a color change indicator, and is formulated in a solid state. The neutralizing absorbent is effective in promptly and safely taking an initial action regardless of the type, nature, and characteristics of acidic, basic, and/or organic chemical substances leaked in the leakage accident of the chemical substance, and accordingly, is useful in preventing secondary accidents. Also, when the neutralizing absorbent is used, there are no concerns about the spread of contamination due to water generated by an acid-base reaction, concerns about the additional occurrence of secondary contamination due to a decontaminating agent can be minimized by using a non-toxic chemical absorbent, and a decontamination process can be visually checked in real time regardless of the type, nature, and characteristics of the leaked chemical substance. Furthermore, when a neutralizer filled with the neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention is used, the leaked chemical substance can be more safely and effectively decontaminated during an initial action.

A coated substrate (2a, 2b) adapted for hydrocarbon adsorption having at least one surface, and a coating on the at least one surface, the coating comprising particulate carbon and a binder, wherein the particulate carbon has a BET surface area of at least about 1300 m.sup.2/g; and at least one of: (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 ml/g and a mesopore volume greater than about 0.5 ml/g. A bleed emission scrubber (1) and an evaporative emission control canister system (30) comprising the coated substrate (2a, 2b) are provided. They can control evaporative hydrocarbon emissions and may provide low diurnal breathing loss (DBL) emissions even under a low purge condition.

The invention provides a method for the production of a zeolite particle composition which has optimized characteristics, such as enhanced adsorption and specific ion exchange properties. A method and an apparatus for producing improved zeolite particle compositions are provided, where the particles are treated with an oxygen-containing gas during micronisation. The zeolite particle compositions can be used in a method for treatment of the human or animal body by therapy and/or prophylaxis, and specifically in a method of treating or preventing conditions of the human or animal body or symptoms of these conditions that are related to heavy metals, endotoxins, exotoxins, and/or bacterial, viral or parasitic intoxications in or of the digestive system, mucosal surfaces or the skin. Also, new zeolite particle compositions can be used as food additive, as filter for purification of water, in packaging materials, or as cosmetic ingredient.

Provided are methods for storing a gas. An example method comprises providing a vessel containing a manifold system and an adsorbent, the manifold system comprising: a gas tubing, a filter disposed over openings in the gas tubing, a pressure relief valve, and an inlet coupled to the gas tubing and the vessel.
