T/BYXT 130-2024 Vegetable pesticide residue absorption and purification agent
Basic Information
Scope
Scope: This document specifies the term definitions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and sales and service requirements for rare earth zeolite purification agents. This document applies to vegetable pesticide residue adsorption and purification agents prepared from natural clinoptilolite as raw material; Main technical content: Physicochemical indicators shall comply with the requirements in Table 1: Table 1 Item Requirement Superior grade First grade Ammonia adsorption value a/(mmol/100g) ≥100.0 ≥95.0 Particle size Passing 0.2mm-0.5mm sieve/ (%) ≥98.0 Passing 0.6mm-0.8mm sieve/ (%) ≥-98.0 Solubility /% ≤50.0 ≤45.0 Gas effective pore diameter (?) ≥4.0 ≥6.0 Active ingredient Silica (SiO2) / (%) ≥50.0 ≥45.0 Alumina (Al2O3) / (%) ≥7.0 ≥6.5 pH value 5.5-7.0 a The content of zeolite and the ammonia adsorption amount are linearly related. According to industry practice, the zeolite content in the product is determined by measuring the ammonia adsorption amount.
