乙二胺四乙酸二鈉鹽二水合物 (EDTA-2NA) - 簡介                                                                            

性質：

EDTA二鈉二水合物是白色結晶粉末，溶解性較好，在水中溶解度較高。其具有良好的螯合性能，能夠與金屬離子形成穩定的絡合物。       製法：

通常通過EDTA酸（乙二胺四乙酸）與氫氧化鈉反應製得EDTA二鈉。然後再結晶脫水得到EDTA二鈉二水合物。   

注意事項：

在大量接觸或吞食的情況下，可能會引起眼睛、皮膚刺激或消化道不適，需要在使用時注意個人防護措施。

Ethylenediaminetetraacetic Acid Disodium Salt Dihydrate (EDTA-2NA) – Introduction

Properties:
EDTA disodium dihydrate is a white crystalline powder with good solubility and relatively high solubility in water. It has excellent chelating properties and can form stable complexes with metal ions.

Preparation Method:
EDTA disodium is usually prepared by reacting EDTA acid (ethylenediaminetetraacetic acid) with sodium hydroxide. It is then crystallized and dehydrated to obtain EDTA disodium dihydrate.

Precautions:
In cases of large exposure or ingestion, it may cause eye irritation, skin irritation, or gastrointestinal discomfort. Appropriate personal protective measures should be taken during use.
