EDTA-CuNa₂, EDTA Copper Salts

CAS No.: 14025-15-1

Molecular Formula: C₁₀H₁₂N₂O₈CuNa₂

Molecular Weight: 397.7

Structural Formula:

Properties:

EDTA-CuNa₂ is a kind of stable water-soluble metal chelate; copper exists in a chelated state. EDTA-Cu can chelate multivalent ferric ions.

Specifications:

Preparation method:

The preparation of EDTA-Cu is generally achieved by reacting ethylenediaminetetraacetic acid (EDTA) with copper salt and sodium salt under appropriate conditions. The reaction process requires a high reaction temperature and neutral or weakly alkaline reaction conditions.

Usage:

EDTA-CuNa₂ is used as a trace element in agriculture. This EDTA copper salt is hard to be biodegraded. The COD (Chemical Oxygen Demand) value is about 560mg/g.

Used as a separating agent, EDTA-CuNa₂ also can be used for foliar fertilizers.

Packing and Storage:

25kg woven bag. Stored in a cool dry place, it must be tightened after being opened.

Safety and hazards:

When using EDTA copper salt, it is important to pay attention to coordinating the experimental conditions and controlling the temperature to avoid the generation of toxic gases. It is necessary to wear appropriate personal protective equipment, such as chemical-resistant gloves, goggles, and a respirator.
