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 under normal temperature and pressure. It can be dissolved 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. In order 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

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。

EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixative, dyeing agent, fiber processing agent, cosmetic additive, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator for the washing and processing of color sensitive materials.

EDTA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。

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

EDTA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。

EDTA 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 metal ions such as ca2+, mg2+, fe2+, fe3+. It is also used as a complexing agent for anaerobic glue, that is, EDTA is used to treat the double ester of methacrylate, remove the transition metal ions, and eliminate the influence that can promote the decomposition of peroxides, which has a very good effect on improving the stability of anaerobic glue.

水處理方面的應用：

Application in water treatment:

EDTA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。

EDTA has a wide range of coordination ability, can form stable chelates with almost all metal ions, and its metal chelates have good solubility under slightly acidic conditions, so it has long been used as an inhibitor of harmful metal ions and a softener of water in the textile industry. Due to the good water solubility of its metal ion chelates, more and more researches and applications have been made in the cleaning of water equipment.

在農業上的應用：

Application in agriculture:

EDTA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，所以在我國的應用量也越來越大，應用范圍也越來越廣。

The Cu, CA, Fe, Mg, Zn and other metal salts of EDTA series chelating agents have the advantages of good solubility and easy absorption, and become a good source of micronutrient fertilizers. Moreover, these chelated metal salts do not affect their solubility after mixing with each other, which is conducive to the use as multi-element composite micronutrient fertilizers. In addition, EDTA has carboxyl groups participating in the reaction, which can generate potassium salts and ammonia salts, and supplement potassium fertilizer and nitrogen fertilizer while supplementing trace elements. Considering the cost and effect comprehensively, it will be the first choice of chelated micronutrient fertilizer for a long time, so it will be applied more and more widely in China.

EDTA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.baiyaowl.cn咨詢了解吧。

EDTA series chelating agents are also widely used in photography, textile, printing and dyeing, papermaking, daily chemicals and chemical analysis. In addition, it should be stored in a cool and ventilated warehouse and sealed. During transportation, it shall be protected from sun exposure, rain and high temperature.
