It includes the following steps: extract trivalent iron ion and divalent iron ion in water phase through organic extractant, get predecessor of; absterge it with secondary distilled water for2-3 times and get pure load metal predecessor of organic phase; mix organic phase of Mg2 and Fe3 with mol rate of 1:2 and introduce them into autoclave, add distilled water according to the rate of 3:1 or 4:1 of organic phase and water phase and airproof it, and then mix it fiercely, stripping with hydrothermal method at temperature between 200 degree C and 300 degree C and make them react for 2.5 hours; cool it to the room temperature under natural condition, separate liquid and centrifugalize it, absterge it with absolute alcohol for 2-3 times and dry it at temperature of 50 degree C for 30-180 minutes, then get product of magnesium ferrite.

包括如下步骤：通过有机萃取剂来萃取水相中的三价铁离子和二价镁离子，制得有机相前驱物；用二次蒸馏水洗涤2-3次，获得纯净的负载金属有机相前驱物；按照Mg 2 和Fe 3 摩尔比1∶2将有机相混合均匀后引入高压釜中，按照有机相与水相的比例为3∶1或4∶1加入蒸馏水，密封后，对溶液进行强力搅拌，水热反萃的温度在200-300℃之间反应2.5小时；自然冷却至室温，分液，离心分离，用无水乙醇洗涤2-3次，在50℃下干燥30-180分钟，得铁酸镁产品。

Therefore can pass to use the cupric sulfate sulfuric acid potassium for the catalyst take sulfuric acid as to carry the body to digest it, make the amino acids chelate match the conversion for dissolve sex easily of ammonium sulfate and white vitriol, then absorb a fixed amount to try the kind to join 40% sodium hydroside combine under the steam heat function make ammonia the spirit swims to leave out, through cool off to respond the born boric acid with boric acid, be got the total nitrogen content by the standard aqua titration of hydrochloric acid immediately after;But the white vitriol can immediately join the hydrochloric acid hydroxylate , fluoride to turn the in order to cover up, carry on the titration but get the content of its zinc with the EDTA mark liquid..

因此可以通过用硫酸铜硫酸钾为催化剂以硫酸为载体将其消化，使氨基酸螯合锌转化为易溶性的硫酸铵和硫酸锌，然后吸取一定量的试样加入40 %的氢氧化钠并在水蒸气高温作用下使氨气游离出来，经冷却与硼酸反应生成硼酸铵，接着由盐酸标准溶液滴定得到总氮含量；而硫酸锌即可加入盐酸羟铵、氟化氢铵为掩蔽剂，用EDTA标液进行滴定而得到其锌的含量。

It can be used as dispersant in pour-cooling water if iron and steel plants, and also used together with organic phosphonate and zine salts in circulation cooling water with high hardness and high alkality.
