Abstract

The invention discloses a green pollution-free mercapto silk adsorbent. The adsorbent comprises the following substances by weight: 15 to 20 parts of silk, 35 to 46 parts of mercaptoacetic acid, 1 to 9 parts of epoxy acetyl methyl linoleate, 5 to 11 parts of trihexyl citrate, 10 to 17 parts of hypochloric acid, 5 to 9 parts of expanded graphite, 3 to 5 parts of triphenyl phosphine, 6 to 7 parts of redispersible latex powder, 11 to 24 parts of a composite fiber, 3 to 14 parts of sawdust of Schefflera arboricola and 11 to 16 parts of starch. The adsorbent provided by the invention has high adsorption efficiency, a fast adsorption speed and good desorption performance; a preparation process for the absorbent is simple, has easily controllable conditions and low production cost and can easily realize industrial production; the absorbent has good physical and chemical stability and excellent mechanical strength; since the absorbent has a large specific surface area, small specific gravity and high mercapto content, the absorbent has high metal adsorption capacity; and the absorbent has the advantages of no pollution to the environment, low production cost, biodegradability of waste, etc.

Description

technical field [0001] The invention relates to a green and pollution-free mercapto silk adsorbent. Background technique [0002] Silk (silk) is a continuous long fiber that is coagulated by the silk liquid secreted by cooked silkworms when they cocoon. It is also called natural silk and is a natural fiber. One of the earliest animal fibers used by human beings. Silk is the lightest, softest and thinnest natural fiber in nature. It can be easily restored to its original shape after the removal of external force. Warm, warm but not dry. Mulberry silk is mainly composed of animal protein, rich in 18 kinds of amino acids necessary for the human body, can promote the vitality of skin cells, and is known as "the second skin of the human body" and "the queen of fiber". The silk fibers of silkworm cocoons are very thin, only 20 to 30 microns, which is one of the most precious ecological resources, a renewable resource, and a very precious long fiber raw material. The application...
