Proper storage of ATMP (liquid or solid form) is essential to maintain its effectiveness and ensure safety. Below are the key guidelines: 1. Storage Conditions Parameter Requirement Reason Temperature 5–40°C (avoid freezing or high heat) Prevents crystallization (solid form) or degradation. Container Plastic (HDPE) or Stainless Steel ATMP is acidic (pH ~2) and can corrode carbon steel. Sealing…
Distinguishing the quality of Hydroxyethylidene Diphosphonic Acid (HEDP) requires evaluating its chemical purity, physical properties, performance efficiency, and stability. Below are key methods and criteria to assess HEDP quality: 1. Key Quality Indicators (1) Active Content (Purity) High-Quality HEDP: Liquid form (50–60% concentration): Active content ≥50%. Solid form (crystalline powder): Purity ≥95%. Test Methods: Potentiometric Titration: Measures phosphonic…
PAA (Polyacrylic Acid) is a widely used water-soluble polymer in water treatment, detergents, and dispersants. Proper packaging and storage are crucial to maintain its stability and performance. 1. Packaging Specifications Aspect Requirements Material Polyethylene (PE) drums or plastic-lined steel containers (corrosion-resistant). Form Liquid (typically 30–50% aqueous solution) or solid powder. Sealing Airtight to prevent moisture absorption (powder) or…
Using polyacrylic acid (PAA) to treat heavy metal ions (e.g., Pb²⁺, Cd²⁺, Cu²⁺, Hg²⁺) in industrial wastewater leverages its carboxylate (–COO⁻) chelation and electrostatic adsorption capabilities. Here’s a step-by-step guide to optimize the process: 1. Mechanism of PAA Chelation Carboxylate Binding: PAA’s –COO⁻ groups form stable complexes with metal ions via bidentate or bridging coordination, especially with transition metals (e.g., Cu²⁺, Ni²⁺) and heavy metals (e.g.,…
PESA is a green, biodegradable scale inhibitor and chelating agent widely used in agriculture for irrigation systems, soil conditioning, and nutrient management. Below are its key applications: 1. Irrigation System Maintenance Prevents Scale & Clogging in Drip/Trickle Irrigation Problem: Hard water (high Ca²⁺, Mg²⁺, HCO₃⁻) causes mineral deposits, clogging emitters. Solution: PESA (5–20 ppm) inhibits CaCO₃, CaSO₄ scale, improving water flow….
To maintain the stability and performance of OA-12, proper packaging and storage conditions are critical. Below are the industry-standard practices: 1. Packaging Specifications Parameter Requirement Rationale Material HDPE (High-Density Polyethylene) drums Prevents oxidation and moisture ingress Lining Polyethylene inner liner (for metal drums) Avoids metal ion contamination Capacity 25 kg, 200 kg, or 1000 kg…
