特性：EDTA 為高效螯合劑，可與多種金屬離子（如 Ca²⁺、Mg²⁺、Fe³⁺、Cu²⁺ 等）形成穩定螯合物。EDTA 2Na 螯合能力穩定，適合一般工業用途；EDTA 4Na 鹼性較高、螯合能力更強，常用於高 pH 系統。
建議用途：
水處理（軟水處理、鍋爐水、循環水系統）
清潔劑與洗劑配方 •電鍍與金屬表面處理
化工製程助劑 • 紡織、造紙工業
化妝品與個人清潔用品（限合規等級）
注意：本品具有刺激性，對黏膜、眼睛和皮膚有腐蝕性，操作時應佩戴適當的個人防護裝備（手套、護目鏡、防護衣）。
儲存：應儲存於陰涼、乾燥、通風處，遠離火源與熱源。避免與水、酸、鹼性物質接觸，建議使用玻璃纖維或塑膠材質的儲罐。
應用：需通過測試確定最佳用量。配製的溶液應隨配隨用，避免長時間存放。
Characteristics: EDTA is a highly effective chelating agent capable of forming stable complexes with various metal ions such as Ca²⁺, Mg²⁺, Fe³⁺, and Cu²⁺. EDTA 2Na is suitable for general industrial applications, while EDTA 4Na provides stronger chelation performance in high-pH systems.
Recommended Use:
Water treatment (water softening, boiler and cooling systems)
Detergents and cleaning formulations
Electroplating and metal surface treatment
Chemical processing aids
Textile and paper industries
Cosmetics and personal care products (compliant use only)
