Abstract
The invention discloses a bean dreg modified adsorbent and a preparation method thereof. The preparation method comprises the steps of juicing from boiled beans to obtain dregs, modifying the dregs with acid liquid, rinsing, filtering, drying, crushing and screening, so as to prepare the bean dreg modified adsorbent.
Description
Technical field
The present invention relates to a kind of sorbent material, particularly a kind of method utilizing living beings slag to prepare adsorbent, belongs to absorbent fields.
Background technology
Along with industrial boom, a large amount of discharges of industrial wastewater, industrial residue, cause the severe contamination of water body, serious threat is produced to biological and health, and one of pollution sources of water pollutions are exactly heavy metal, heavy metal pollution refers to the environmental pollution caused by heavy metal or its compound, caused by the factors such as mining, toxic emission, sewage irrigation and use heavy metal goods.
Heavy metal contaminants generally has potential hazard.They are different from organic pollution, and the microorganism in water is difficult to make it to decompose eliminate, and in the water of " shrimp eats planktonic organism, and small fish eats shrimp, and big fish swallowing little fish ", food chain is by enrichment, and concentration strengthens step by step.And people is in the terminal of food chain, by food or drinking-water, Toxic is taken in human body, if these Toxics are not easily drained, will put aside in human body, cause slow poisoning.Some heavy metal in vivo can be the organic compound that toxicity is larger by microbial conversion again, such as well-known water marquis is sick to cause containing methyl-mercuric chloride by institute's ichthyophagy, " itai-itai " is then caused by cadmium (Cd) pollution, and these world-shaking public hazard incidents are all containing these caused by heavy metal in the sewage of plant emissions.Therefore, Heavy Metal Pollution is the focus of Research of Environmental Sciences always.
Conventional minimizing technology comprises the methods such as ion-exchange, counter-infiltration, chemical precipitation, redox, membrane filtration and absorption.In all multi-methods, absorption method is as a kind of effectively waste water treatment technique of economy, causes the attention of numerous researcher in recent years.Because active carbon is expensive, regeneration difficulty, makes it be restricted in the use of developing country.Therefore, many researchers start to be devoted to find some unconventional adsorbents and carry out alternative active carbon.Achieved some progress both at home and abroad in this respect, as some plant tissues and some agriculturals, industry and the living beings byproduct etc. of pharmacy industry, research finds that their heavy metal have higher clearance and with low cost.As Thuja orientalis living beings, flyash, rice husk, wheat shell, sawdust and sunflower leaf etc. prove it is all good active carbon substitute after deliberation.
Bean dregs are as the refuse produced in bean product manufacture craft, and output is very large.But due to its perishability and the inconvenience that stores in transport, most bean dregs are all gone out of use, does not realize its value and to environment.Being reclaimed by bean dregs and utilizing is the process method of disposal meeting recycling economy, turn waste into wealth.Therefore, utilize bean dregs as a kind of low cost and the new bio adsorbent with environmental benefit has important researching value for the heavy metal removed in water body.The present invention take bean dregs as raw material, carries out process prepare a kind of modified adsorbent by the method for chemistry, physics.
Summary of the invention
The object of this invention is to provide a kind of bean dregs modified adsorbent, its preparation method comprises the steps:
(1) get proper amount of fresh bean or pea to clean, to be immersed in clear water more than 10 hours;
(2) pull the bean or pea after immersion out, put into distilled water and boil;
(3) the bean or pea after boiling are squeezed the juice and get slag;
(4) slag is immersed in certain density acid solution, heating water bath a period of time;
(5) again that solution rinsing is extremely neutral, filter;
(6) the filter residue filtered is dried, pulverizing;
(7) by powder pulverized powder, sieve, collect powder and namely obtain product.
Preferentially, step (2) in boiling time control at 1-2 hour.
Preferentially, step (4) middle acid solution of adding is formaldehyde-HCl solution, and wherein formaldehyde solubility is 10-20%, HCl solubility is 0.1-0.15mol/L.
Preferentially, step (4) middle water bath heating temperature controls at 60-70 DEG C, heat time control 2-3 hour.
Preferentially, step (6) in, filter residue bake out temperature is 75-85 DEG C.
The present invention has following advantages and characteristic:
(1) abundant raw material, cost is low;
(2) advantages of good adsorption effect, environmental friendliness.
