Description
Technical field
The present invention includes the separation method with solid absorbent treatment liquid, especially a kind of using attapulgite modified
The method that composite chelate resin removes sea cucumber heavy metal.
Background technology
Sea cucumber typically lives in 3-20 meters of deep marine sites, perches in water-bed rock, silt, sea grass.They like gulping down
Food is deposited on silt, the beach face ooze in seabed, because wherein containing diatom, zoodetritus, small-sized biological, microorganism etc..Sea cucumber
It is slow-growing, 2-3 is generally required from seedling to maturation.Because offshore waters, by different degrees of pollution, are added in recent years
The special life habit of sea cucumber, sea cucumber surface and digestion enteron aisle easily accumulate heavy metal.At present, Holothurian machining processing is general passes through
The conventional method that surface washing dissection is washed again, can only typically remove sea cucumber sediments, but can not effectively remove
The harmful substances such as heavy metal ion, these harmful substances are stayed in sea cucumber, are caused harm to the mankind.Therefore, how sea cucumber is removed
The harmful substance such as heavy metal is a urgent problem to be solved in surface and enteron aisle.
The content of the invention
In order to overcome the shortcomings of that conventional method cleaning sea cucumber can not effectively remove heavy metal in sea cucumber body, the purpose of the present invention
It is to provide the attapulgite modified composite chelate resin of utilization that a kind of rational technology, adsorption effect are good, easy to operate, cost is low
The method for removing sea cucumber heavy metal.
The technical solution adopted for the present invention to solve the technical problems is：One kind utilizes attapulgite modified composite chelate tree
The method that fat removes sea cucumber heavy metal, it is characterised in that：It passes through following process steps：
(1) preparation of attapulgite-chelating resin：5~15 parts of pretreated attapulgites, 20 are weighed by weight
~40 parts of D405 chelating resins are placed in container, and 15~25 parts of addition, the HCL solution that concentration is 2~4mol/L, heating are boiled,
Sonic oscillation shakes up 0.5~1.5h, and supersonic frequency control is 20~48KHZ, centrifuges 15~30min, removes supernatant, takes precipitation to use
Deionized water is washed till pH value 6~8, and 6~8h is dried under the conditions of 70~80 DEG C, and grinding and sieving is placed in drier, produced recessed
Convex rod soil-chelating resin；
(2) preparation of attapulgite-chelating resin aqueous suspensions：In terms of attapulgite quality, quality is prepared with deionized water
Fraction is 1~3% attapulgite-chelating resin aqueous suspensions, standby；
(3) removal of sea cucumber heavy metal：Pretreated sea cucumber is put into attapulgite-chelating resin aqueous suspensions, sea
The mass ratio for participating in attapulgite-chelating resin aqueous suspensions is 1:1~2,20~30min of sonic oscillation, supersonic frequency at room temperature
Control for 20~60KHZ, then to take out sea cucumber, rinsed 2~3 times with clear water, you can.
The pretreatment of the attapulgite be by attapulgite with 60~80% ethanol soak 10~15h, it is clear with distilled water
Wash clean.
The pretreatment of the sea cucumber is to be drawn after sea cucumber belly is splitted except enteraden, and sea cucumber surface silt particle, dirt are removed with clear water
Dirt and internal organ.
The present invention is combined with chelating resin using the attapulgite of pretreatment and prepares attapulgite-chelating resin, then is spent
Ionized water prepares attapulgite-chelating resin aqueous suspensions, and sea cucumber is cleaned using the aqueous suspensions sonic oscillation, removes the weight in sea cucumber
Metal, obtains the beche-de-mer products that content of beary metal declines to a great extent after absorption.Its attapulgite used has larger
Specific surface area, and adsorb that least concentration is low, it is short to reach time of equilibrium adsorption, to adsorption conditionses without rigors, to Cu (II),
Cd (II), Ni (II) and Cr (VI) have preferable adsorption effect, wherein to Cr (VI) adsorption capacity highest, and price is just
Preferably, raw material is easy to get；Chelating resin（chelate resins）It is that a class can form the crosslinking of many coordination networks and thing with metal ion
Functional high molecule material, the mechanism of its adsorbing metal ions is that with metal ion complexation reaction occurs for the function atom on resin,
The rock-steady structure of similar small molecule chelate is formed, and the mechanism of ion exchange resin absorption is electrostatic interaction, therefore chelating tree
The adhesion of fat and metal ion is stronger, and selectivity is higher.Chelating resin is combined by the present invention with attapulgite, is both added
The surface area of absorption, increases effective adsorption site, thus adsorbance increase again.The process that the present invention is obtained by above-mentioned steps
The beche-de-mer products of absorption, according to《Chinese Pharmacopoeia》Atomic absorption spectrophotometry in annex lead, cadmium, arsenic, determination method is examined
Survey, the content of beary metal in sea cucumber is significantly reduced, and is reached food sanitation standard, is greatly improved the security of product.
