Abstract

The invention discloses novel mercury-free environmentally-friendly hematoxylin dyeing liquid and a preparation method thereof and belongs to the technical field of a pathological experiment. The dyeing liquid is mainly prepared by the following raw materials: hematoxylin, a mordant reagent, an oxidizing agent, acid, ethylene diamine tetraacetic acid disodium salt, iso-tridecanol polyoxyethylene ether, glycerin and water; a Mordant is any one of aluminum potassium sulfate dodecahydrate, aluminum sulfate, ferric trichloride and copper sulfate; the oxidizing agent is any one of sodium iodate andpotassium permanganate; the acid is any one of acetic acid, hydrochloric acid and citric acid. The novel mercury-free environmentally-friendly hematoxylin dyeing liquid disclosed by the invention successfully solves the problem of HE dyeing troubled in the medical pathological diagnosis field for a long term, for example, hematoxylin dyeing liquid is poor in stability and short in shelf life, isprovided with a metal film, has dye residues, foams and is unclear in corpuscular contrast, unclear in level and dark in nuclear dyeing color and the like.

Description

technical field [0001] The invention relates to a novel mercury-free environment-friendly hematoxylin dye solution and a preparation method thereof, belonging to the technical field of pathological experiments. Background technique [0002] Hematoxylin stain is a routine nuclear stain in pathology laboratories, and its formulations are also varied. The main differences between the common hematoxylin dyes on the market are: 1. The oxidants are different. There are long-term natural oxidation, rapid oxidation using mercury oxide and potassium permanganate oxidant, and slow oxidation using sodium iodate oxidant; Second, the difference of mordant. Common mordants are aluminum sulfate, ferric chloride, potassium aluminum sulfate dodecahydrate, copper sulfate, etc.; 3. The acids used are different. Commonly used acids are acetic acid, hydrochloric acid, citric acid, etc. [0003] But in general, each formula of hematoxylin dye solution has common problems: 1. Excessive oxidatio...
