A provided novel colloid active component, a method for manufacturing colloid aluminum silica gel, and a surfactant containing the same are disclosed for solving water and land pollution, being safe to a human and the ecosystem, and adding economic value and applicability for the industrial use, wherein the method comprises the steps of: (a) dissolving a mixture of aluminum oxide, silicic acid, potassium, iron oxide, sulfuric acid and water into sulfuric acid; (b) adding potassium sulfate solution into the solution, and stirring at a low temperature to produce compositions with soluble aluminum double salt; (c) purifying the compositions to get very pure and dense aluminum potassium sulfate; (d) adding aluminum silicate and water to produce alkali metal polysilicate-sulfate water salt chelate; (e) polymerizing and precipitating the resultant at a low temperature to produce pectograph of aluminum silicate sieve; (f) producing chelate by adding Mgo, Fe2O3, Ca(OH)2, NaOH, KOH, and distilled water in sequence; (g) purifying and drying the chelate to get dried microsphere; (h) melting the microsphere, cooling, hardening, and mixing with thin sulfuric acid; (i) polymerizing, cleansing, heating, dehydrating, or drying, and performing vapor treatment to obtain powdered and highly absorptive aluminum silicate molecular sieve with under 1 &mgr;m of granularity; and, (j) polymerizing the aluminum silicate molecular sieves with each other until they are matured to be a highly dense heel.
