Embodiment 1

[0019] Example 1 Preparation of cellulose acetate filamentous adsorbent material and its efficiency in removing o-xylene.

[0020] The method for preparing the above-mentioned cellulose acetate filamentous adsorbent material comprises the following steps:

[0021] (1) Film liquid preparation: cellulose acetate 12g, acetone 65g, dioxane 3g, magnesium perchlorate 3g, water 16g, Tween 80 1g; Inside the bottle, place the Erlenmeyer flask containing the above prepared membrane solution in a constant temperature shaking box at a temperature of 30-45°C until it is completely dissolved, then use ultrasonic treatment for 10-20 minutes to make the membrane solution more evenly dispersed.

[0022] (2) Adopt the device shown in the accompanying drawings of the specification, put the above prepared membrane liquid into the liquid storage tank (2), apply a certain pressure through the liquid storage tank cover (1), and the membrane liquid passes through a plurality of needle-shaped syringes...

Embodiment 2

[0025] Embodiment 2 prepares the cellulose acetate filamentary adsorption material containing iron oxide and removes H 2 S potency.

[0026] (1) Membrane solution preparation: cellulose acetate 20g, acetone 90g, dioxane 4g, magnesium perchlorate 5g, water 16g, Tween 80 1g, FeCl 3 15g; put the weighed material in an Erlenmeyer flask with a ground stopper, and place the Erlenmeyer flask containing the above-prepared film solution in a constant temperature oscillation box, and keep the temperature at 30-45°C until it is completely dissolved , and then use ultrasonic treatment for 10 to 20 minutes to make the film liquid more uniformly dispersed.

[0027] (2) Adopt the device shown in the accompanying drawings of the specification, put the above prepared membrane liquid into the liquid storage tank (2), apply a certain pressure through the liquid storage tank cover (1), and the membrane liquid passes through a plurality of needle-shaped syringes ( 3) Drop into the container (4)...

Embodiment 3

[0031] Example 3 Preparation of another cellulose acetate filamentous adsorbent material containing iron oxide and its performance in removing styrene.

[0032] The method for preparing the adsorbent is as in Example 2, and its membrane solution is prepared as follows: cellulose acetate 12g, acetone 60g, dioxane 3g, magnesium perchlorate 3g, water 16g, Tween 80 1g, ferric nitrate 20g; The weighed materials are placed in a conical flask with a ground stopper, and the conical flask containing the above-mentioned prepared film solution is placed in a constant temperature oscillation box, and the temperature is kept at 30-45°C until it is completely dissolved, and then used Ultrasonic treatment for 10-20 minutes makes the film liquid more evenly dispersed.

[0033] Fill the above-mentioned adsorbent in an adsorption column with a diameter of 2cm and a height of 18cm. The filling height of the adsorbent is 15cm. The odor passes through the adsorption column from bottom to top, and ...

Abstract

The invention relates to an acetate silk based absorbent to remove odor. It only has acetate with proper amount of metal oxidation according to requirement. It resolves acetate into the organic solution by adding metal compound and dioxygen six ring additive to get the evenly mixed film solution. It drops the film solution into thread and condensed it in water. If added metal compound, dipping the absorbent in the diluted ammonia for 5-10min, keeping temperature 15-25deg.C. This fiber could be white with acetate silk absorbent or with red brown oxide-magnet.

Description

1. Technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a filamentous adsorption material mainly composed of cellulose acetate and added with metal oxides for absorbing and removing odor and a preparation method thereof. 2. Background technology [0002] At present, a lot of research and development and engineering practice have been carried out for the treatment of conventional pollutants such as industrial wastewater, urban domestic sewage, atmospheric smoke, sulfur dioxide, nitrogen oxides, and solid waste, and good progress has been made. During the generation, discharge or treatment of the above pollutants, foul-smelling substances will be generated and emit bad smell. Although the concentration is low, it will produce strong sensory stimulation. Some odors are toxic and seriously endanger human health and the ecological environment. Developed countries have started research and development of odor control tech...
