Description

A kind of foam coppe ferrite and its preparation and application using organic polyurethane foam as substrate
(1) technical field
The present invention relates to a kind of foam coppe ferrite using organic polyurethane foam as substrate and preparation method thereof and the bubble Application of the foam coppe ferrite in Adsorption arsenic in water body.
(2) background technology
Arsenic has Half-metallic, through improving alloy property frequently as alloy addition, for example, a small amount of arsenic is added in copper Arsenical copper, which is made, can significantly reduce the thermal conductivity and electric conductivity of copper.It is applied in addition, arsenic is also often used as dopant material Prepare some semi-conducting materials.The metallic compound of native arsenic or arsenic is extremely rare in nature, and they are mostly with sulfide Form be mixed in other metallic ores, such as in copper, lead, zinc and cobalt ore.Exploitation and smelting with the mankind to arsenic-containing ores, with And arsenide utilizes etc. the behavior directly or indirectly to affect arsenic migration in the environment and conversion process extensively.The opposing party Face, arsenic and its compound are the carcinogenic substances that many authoritative institutions generally acknowledge in the world, and excess intake arsenic can cause very big danger to human body Evil.After arsenic is absorbed by the body, trivalent arsenic may interfere with the reaction that internal phosphorus is participated in, and such as hinder the synthesis of atriphos, arsenic is also It can be reacted with the sulfydryl of zymoprotein in body, enzyme is lost activity, cell eubolism is influenceed, so as to cause histologic lesion and machine Body obstacle, directly results in poisoning even dead.Chronic Drinking water endemic arsenism can cause harm to human body multisystem function, cause as The diseases such as hypertension, cardiovascular and cerebrovascular diseases, diabetes, skin pigment metabolic disorder, and finally develop into cutaneum carcinoma.In recent years, with The quickening of process of industrialization, the arsenic pollution that industrial production is brought constantly expands, and the murder by poisoning of arsenic in water body at home and abroad has phase Close report.
The international research mechanism such as World Health Organization unanimously assert that arsenic is that a kind of high poison element is also priority acccess control in water body One of pollutant.The arsenic of different shape, toxicity is also different, and in general the toxicity of inorganic arsenic is bigger than organo-arsenic, trivalent arsenic Toxicity it is bigger than pentavalent arsenic, and among the compound of arsenic, the toxicity of arsenic hydride is far longer than other arsenates and arsenite. In worldwide, the acute or chronic arsenic poisoning because of caused by drinking water by arsenic pollution, and cause the diseases such as various cancers Disease, or even dead case frequently occur, and these startling data have caused great attention of the people to Arsenic in Drinking Water. 1993, regulation arsenic content was limited to 10 μ g/L, world community in the new drinking water standard that the World Health Organization formulates This standard is adopted one after another, and maximum allowable arsenic content standard in drinking water is brought up into 10 μ g/L from 50 original μ g/L.
The method of removing arsenic in water common at present has Coagulation Method, ion-exchange, absorption method, oxidation-precipitation method, bioanalysis Etc..Absorption method is the prefered method of Removal of Arsenic in Drinking Water, the active aluminum oxide of common adsorbent, titanium oxide, zeolite, ferrimanganic Compound etc., this method is easy to operate, and adsorbent is cheap, it is adaptable to factory's water body arsenic pollution processing.But powder is inhaled Attached dose is difficult to reclaim and reuses, or even powder itself can produce secondary pollution to water body, thus is not suitable for lake, river Arsenic pollution Deng water body in large is handled.
Therefore, a kind of new and effective repeatable adsorbent utilized is studied, the improvement for water body arsenic pollution has very Important meaning.
