Embodiment 1

[0030] Embodiment one, the processing technology of brown algae biosorbent material of present embodiment comprises the following steps:

[0031] A, soaking brown algae plants with a concentration of 1% hydrochloric acid solution, and processing the brown algae plants after hydrochloric acid treatment into powder, the number of parts of the hydrochloric acid solution is 5 times the number of seaweed plants;

[0032] B. Mix chitosan with dilute acid solution. According to the weight ratio, chitosan accounts for 0.5 part in every 100 parts, and the rest is the parts of dilute acid solution. After mixing, chitosan dilute acid solution is formed. Dilute chitosan acid The solution is mixed with the powdered seaweed plant in step A and then extruded under pressure. In proportion by weight, every 100 parts of the chitosan dilute acid solution accounts for 99.5 parts, and the rest is the parts of the seaweed plant. The dilute acid solution is the concentration 0.5% acetic acid aqueous...

Embodiment 2

[0036] Embodiment two, the processing technology of seaweed biosorbent material of this embodiment comprises the following steps:

[0037] A, soaking the seaweed plants with a concentration of 10% hydrochloric acid solution, and processing the seaweed plants after the hydrochloric acid treatment into powder, in proportion by weight, the number of parts of the hydrochloric acid solution is 20 times the number of parts of the seaweed plants;

[0038] B. Mix chitosan with dilute acid solution. According to the weight ratio, chitosan accounts for 5 parts in every 100 parts, and the rest is the parts of dilute acid solution. After mixing, chitosan dilute acid solution is formed. Dilute chitosan acid The solution is mixed with the powdered seaweed plant in step A and then extruded under pressure. In proportion by weight, the chitosan dilute acid solution accounts for 95.0 parts per 100 parts, and the rest are the parts of the seaweed plant. The dilute acid solution is the concentrati...

Embodiment 3

[0042] Embodiment three, the processing technology of seaweed biosorbent material of the present embodiment comprises the following steps:

[0043] A, soaking the seaweed plants with a concentration of 5% hydrochloric acid solution, and processing the seaweed plants after hydrochloric acid treatment into powder; by weight ratio, the number of parts of the hydrochloric acid solution is 10 times the number of seaweed plants;

[0044] B. Mix chitosan with dilute acid solution. According to the weight ratio, chitosan accounts for 3 parts in every 100 parts, and the rest is the parts of dilute acid solution. After mixing, chitosan dilute acid solution is formed. Dilute chitosan acid The solution is mixed with the powdered seaweed plant in step A and then extruded under pressure. In proportion by weight, the chitosan dilute acid solution accounts for 98 parts per 100 parts, and the rest are the parts of the seaweed plant. The dilute acid solution is the concentration 2% aqueous solu...

Abstract

The invention discloses a preparation method and application of biosorption material prepared from seaweed plants and chitin amine. The preparation method includes pretreating seaweed plants with the hydrochloric acid solution to eliminte the swelling capacity of alginic acid in the seaweed plants after protonized; and pulverizing the seaweed plants to evenly dispers the seaweed plants in a chitin amine solution to obtain the dispersion. After the dispersion is dropped or extruded into an alkali solution, the chitin amine is precipitated, the seaweed plants dispersed in the solution is coated in the chitin amine, and alginic acid in the seaweed plants is also converted into the water-soluble sodium alginate. The biosorption material is used for treating heavy metal ions-containing waste water with a remarkable effect. The chitin amine can adsorb heavy metal ions by chelation, and sodium alginate in the seaweed plants can combine with heavy metal ions by forming water-insoluble salt. The adsorbed heavy metal ions can be conveniently separated from the waste water.

Description

technical field [0001] The invention relates to a processing technology of biological materials, in particular to a preparation method and application of biological adsorption materials prepared from seaweed plants and chitosan. Background technique [0002] With the rapid development of the economy, a large amount of waste water is discharged, the accumulation of heavy metals in soil and water sources is intensified, and the pollution of heavy metals is also becoming more and more serious. Because heavy metals are easy to bioaccumulate through the food chain, they pose a serious threat to organisms and human health. How to effectively control heavy metal pollution has become a common concern of mankind. [0003] A lot of research has been done on the treatment of heavy metal pollution at home and abroad. The wastewater treatment methods that have been developed and applied mainly include chemical methods, physical chemical methods and biological methods, including chemica...
