Basic Information
Scope
Scope: This document specifies the terminology definitions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and sales and service requirements for crystalline hydrated aluminosilicate. This document is applicable to crystalline hydrated aluminosilicate aflatoxin adsorbent products prepared from natural clinoptilolite as raw material; Main technical content: Physicochemical indicators shall meet the requirements of Table 1: Table 1 Item Indicator Requirements Superior Grade First Grade Ammonia Adsorption Value a/(mmol/100g) ≥100.0 95.0 Particle Size b /% ≤95.0 90.0 Dry Loss (Mass Fraction) /% ≤6.0 10.0 Moisture /% ≤10.0 12.0 Solubility /% ≤50.0 45.0 Gas Effective Pore Size (?) ≥4.0 6.0 Water Absorption /% ≤60.0 55.0 Alumina (Al2O3) /(%) ≥7.0 6.5 Silica (SiO2) /(%) ≥50.0 45.0 Aflatoxin B1 Adsorption Rate /% ≥99.0 90.0 pH Value 5.5–7.0 a The content of zeolite is linearly related to the ammonia adsorption quantity. According to industry practice, the zeolite content in the product is determined by measuring the ammonia adsorption quantity. b The particle size is calculated by passing through a 0.9mm sieve.
