In addition to an anti-extraction of iron ions from the iron-rich liquid method

The present invention provides an iron-rich ionic liquid from the stripping method of removing iron, in particular mixed ionic liquid Aliquat336 pure iron and hydrochloric acid, the reaction solution was extracted, the organic phase obtained iron-rich; sodium sulfite as an anti-stripping agent, by using sodium sulfite hydrolysis and reduction characteristics in an aqueous solution of the ionic liquid iron-rich were stripped iron, iron a stripping rate of 90%, far greater than a conventional sulfuric acid, hydrochloric acid, water as a stripping stripping agent efficiency; ionic liquid after addition of iron in hydrochloric acid for regeneration can be reused again, does not affect the subsequent use. Compared with the prior art method, the high stripping efficiency, simple procedure, a small amount of ionic liquid loss, a high concentration obtained iron-rich stripping solution may further be prepared iron products.
