Description
Technical field
The present invention relates to a kind of preparation method of natural zeolite suspension, concrete use natural zeolite, polysaccharide and edible acid are as raw material, prepare a kind of suspension of natural zeolite, and the application of this suspension in Adsorption of Heavy Metals, absorbing toxin, suppression viral growth and promotion nutrient absorption etc.
Background technology
Along with the fast development of society and the growth in the living standard of people, environmental pollution becomes more serious, and food-safety problem also emerges in an endless stream, and therefore the safety of people to the health of health and life is also more and more pay close attention to.The development of industry agricultural, causes large-area soil contaminated by heavy metals; The use of agricultural chemicals, herbicide, also makes it a large amount of remaining in soil and crops; Thus not only pollute soil and groundwater resources, also pollute the grain that the mankind depend on for existence, vegetables, melon and fruit etc., also made the enrichment in human body of heavy metal ion and organic pollution.What this was serious destroys ecological environment, also compromises the health of the mankind greatly.For ensureing the health of the health of the stable of ecological environment and the mankind, organic contamination substrate concentration, the concentration of heavy metal ion in effective method reduction soil, food and human body must be taked, strengthen the immunocompetence of human body self simultaneously.
The method that tradition gets rid of vivotoxin mainly comprises traditional Chinese medical science toxin expelling eight treating observances, foot bottom massage function toxin expelling, breakfast 3 glasss of water toxin expellings, fruit toxin expelling, Herb Tea toxin expelling method, popular treatment for sunstroke by scraping the patient's neck, chest or back toxin expelling, vegetable juice toxin expelling, the U.S. face fruit of toxin expelling, hydrotherapy/popular treatment for sunstroke by scraping the patient's neck, chest or back/massage, intestinal lavage toxin expelling, detoxicating intestine, enteron aisle ecological toxin expelling, jejunitas toxin expelling, half jejunitas toxin expelling method etc.But all there are some problems in actual applications in above-mentioned toxin expelling method.Absorption toxin expelling rule relies on intensive pore structure and huge specific area on adsorbent, or the chemical bond by being formed between various active group preparation adsorbent on the surface, can selectively adsorption and enrichment heavy metal ion and organic pollution, cells in vivo can also be stimulated simultaneously to make it strengthen immunocompetence and promote that matrix is to the absorption of nutriment.And then reach the object of heavy metal ion and organic pollution materials in removing body, enjoy domestic and international expert's extensive concern at present.
Natural zeolite (Natural Zeolite) is the silicates mineral that a class distribution is very wide, have loose structure.Be made up of the silicon-oxy tetrahedron linked together by shared oxygen and the three-dimensional screen work of aluminum-oxygen tetrahedron, the superfluous negative electrical charge that trivalent aluminium replaces the generation of tetravalence silicon balanced by the metal cation (being generally alkali metal or alkaline earth metal cation) of monovalence or divalence.Usually stronger cation exchange capacity (CEC) is possessed, can heavy metal ion in removing body, also can stop the breeding hyperplasia of body inner virus cell.But natural zeolite is but not enough to the removal ability of organic pollution.Adopt " micro-nano ", roasting and acid-treated natural zeolite can significantly improve the Scavenging activity of natural zeolite to organic pollution.But the suspension stability of natural zeolite solution is still very poor.
Although there has been the report about removing organic pollutants and heavy metal ion with the modified natural such as cationic surfactant, shitosan zeolite at present, the stability of the product of acquisition is bad, is difficult to industrialized application.
