EDTA常溫常壓下為白色粉末，能溶于氫氧化鈉、碳酸鈉及氨溶液中，能溶于沸水，微溶于冷水，不溶于醇及一般有機溶劑。為了更好的使用它，下面跟著氫氧化鉀廠家來充分了解EDTA的特性及產品用途吧。

EDTA is a white powder at normal temperature and pressure, soluble in sodium hydroxide, sodium carbonate, and ammonia solutions, soluble in boiling water, slightly soluble in cold water, and insoluble in alcohol and general organic solvents. To better use it, let's follow the potassium hydroxide manufacturer to fully understand the characteristics and product uses of EDTA.

EDTA的特性

Characteristics of EDTA

是一種重要的絡合劑。EDTA用途很廣，可用作彩色感光材料沖洗加工的漂白定影液，染色助劑，纖維處理助劑，化妝品添加劑，血液抗凝劑，洗滌劑，穩定劑，合成橡膠聚合引發劑。

It is an important complexing agent. EDTA is widely used as a bleaching and fixing solution for the processing of color sensitive materials, dyeing aids, fiber treatment aids, cosmetics additives, blood anticoagulants, detergents, stabilizers, and polymerization initiators for synthetic rubber.

是螯合劑的代表性物質，能和堿金屬、稀土元素和過渡金屬等形成穩定的水溶性絡合物。除鈉鹽外，還有銨鹽及鐵、鎂、鈣、銅、錳、鋅、鈷、鋁等各種鹽，這些鹽各有不同的用途。

It is a representative substance of chelating agents and can form stable water-soluble complexes with alkali metals, rare earth elements, and transition metals. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, and aluminum, which have different uses.

是一種優良的鈣、鎂離子螯合劑，用作乳液聚合所用水的螯合劑，除去Ca2+、Mg2+、Fe2+、Fe3+等金屬離子。也用作厭氧膠的絡合劑，即用EDTA處理甲基丙烯酸雙酯，除去過渡金屬離子，能促進過氧化物分解的影響，對提高厭氧膠穩定性的效果非常好。

It is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water used in lotion polymerization to remove Ca2+, Mg2+, Fe2+, Fe3+and other metal ions. It is also used as a complexing agent for anaerobic adhesives, that is, using EDTA to treat diester methacrylate to remove transition metal ions and eliminate the effects that can promote peroxide decomposition, which has a very good effect on improving the stability of anaerobic adhesives.

水處理方面的應用：

Applications in water treatment:

具有廣泛的配位能力，能與幾乎所有的金屬離子形成穩定的螯合物，而且其金屬螯合物在微酸性條件下具有良好的溶解性，所以很早就在紡織行業中用做有害金屬離子的抑制劑和水的軟化劑。由于其金屬離子螯合物的水溶性很好，在用水設備的清洗方面的研究和應用越來越多。

With a wide range of coordination capabilities, it can form stable chelates with almost all metal ions, and its metal chelates have good solubility under slightly acidic conditions. Therefore, they have long been used as inhibitors of harmful metal ions and water softeners in the textile industry. Due to the excellent water solubility of its metal ion chelates, there is increasing research and application in the cleaning of water equipment.

在農業上的應用：

Application in agriculture:

系列螯合劑的Cu、Ca、Fe、Mg、Zn等金屬鹽具有溶解性能好、易吸收等優點，成為微肥的良好來源，并且這些螯合態的金屬鹽相互混合后不影響其溶解性能，有利于作為多元復合微肥使用。而且EDTA有參與反應的羧基，可以生成鉀鹽、氨鹽等，在補充微量元素的同時，補充鉀肥和氮肥。對成本和效果進行綜合考慮，它在很長一段時間內將會是螯合態微肥的選擇，所以在我國的應用量也越來越大，應用范圍也越來越廣。

The metal salts such as Cu, Ca, Fe, Mg, Zn, etc. of the series of chelating agents have the advantages of good solubility and easy absorption, making them a good source of micronutrient fertilizers. Moreover, the mixing of these chelating metal salts does not affect their solubility, which is conducive to their use as multicomponent composite micronutrient fertilizers. In addition, EDTA has carboxylic groups that participate in the reaction and can generate potassium salts, ammonia salts, etc. While supplementing trace elements, it can also supplement potassium and nitrogen fertilizers. After comprehensive consideration of cost and effect, it will be the choice of chelated micronutrient fertilizer for a long time, so its application amount and scope in China are also increasing.

系列螯合劑在照相、紡織、印染、造紙、日化、化學分析等方面也有廣泛應用。另外要注意儲存于陰涼、通風的庫房，密封保存。運輸途中應防曝曬、雨淋，防高溫。更多相關內容就來我們網站http://www.yiqijieneng.cn咨詢了解吧。

A series of chelating agents are also widely used in photography, textiles, printing and dyeing, papermaking, daily chemicals, chemical analysis, and other fields. In addition, attention should be paid to storing in a cool and ventilated warehouse, sealed and stored. During transportation, it should be protected from sunlight, rain, and high temperatures.
