摘要： A method for removing a halogen-containing gas, which comprises contacting a halogen-containing gas generating at least one selected from the group consisting of HF, HCl, HBr and HI when contacted with water with granules comprising a solid base and a carbonaceous material in amounts of 60 to 99.9 mass % and 0.1 to 40 mass %, respectively, based on the total mass of the granules in the presence of water. The solid base is preferably sodium hydrogen carbonate, and the carbonaceous material is preferably an activated carbon having an average pore radius of 0.1 to 50 nm and a pore volume of 0.05 to 4 cm3/g. The method is advantageous in that the generation of heat by an adsorbent is suppressed, it exhibits an improved capability of treating a halogen-containing gas, the generation of odor by spent adsorbents and solid wastes is reduced, and the completion of a reaction can be easily judged.

摘要： A composite sol which is capable of forming an ink-receiving layer having high transparency and the high ability to fix colorants. The sol is a colloidal solution comprising an aqueous medium and aggregate particles dispersed therein each comprising silica and alumina, wherein the primary silica particles are spherical and have an average particle diameter of 2 to 200 nm, the aggregate particles have an average particle diameter which is at least two times that of the primary silica particles and not larger than 1,000 nm and have a z-potential of +10 mV or higher, and the solution has a pH of 3 to 9. One process for producing the silica-alumina composite sol comprises gradually adding to a silica sol an aluminum salt which, upon dissolution in water, gives an acid solution. The other process comprises mixing a silica sol with an alumina sol which, upon drying, gives a xerogel having a specific surface area of 150 m2/g or larger to thereby form aggregate particles comprising silica and alumina, and then deflocculating the particles.
