Abstract
The invention relates to a metal ion adsorbent prepared by using gutter oil as a raw material. The metal ion adsorbent can extract and absorb a plurality of metal ions in a solution, and the adsorbent can be regenerated through a desorption solution, thereby realizing cycle utilization of the adsorbent. The adsorbent provided by the invention has no volatile toxicity, good fluidity and relatively high adsorption efficiency. An object of treating wastes by using wastes can be achieved if the adsorbent is applied in the fields of waste water treatment, wet metallurgy or recycle of electronic wastes, with low cost and small secondary pollution. The adsorbent provided by the invention is characterized in that a modifier prepared by one or more medicaments is added into the gutter oil according to metal ion species in a to-be-adsorbed solution; and the solution is heated and stirred for 0.1-5 hours at a temperature of 40-150 DEG C under a pressure of 50-200 kPa and then subjected to ultrasonic treatment for 0.1-5 hours, so that the metal ion adsorbent can be prepared by using the gutter oil.
Description
Technical field
The present invention is a kind of metal ion adsorbent that waste oil makes as Raw material processing of take, and can, to the many kinds of metal ions extraction absorption in solution, can be used for wastewater treatment, hydrometallurgy or recycling of WEEE field.
Background technology
In enrichment solution, in the process of metal ion, common extractant mainly contains ion exchange resin, organic extractant, biomaterial, zeolite, active carbon and activated sludge.Patent CN1792834 sorbent material used is feather, but this material does not have mobility, and little with solution contact-making surface, and adsorption efficiency is low, can not regenerate.It is solid-state that the nylon membrane of patent CN101249990 also becomes, and preparation process and regenerative process be more complicated all.Patent CN1396280 be take hydroxyl-ketoxime and is carried out the extraction of copper as main component, and this material volatility is stronger, and toxicity is larger, and cost is higher.Patent CN101415848 reclaims nickel and cobalt with ion exchange resin, and this technique can reclaim the metal ion in ore leachate preferably, but the complicated process of preparation of resin itself, cost is higher, and corollary equipment specification requirement is high, wayward.Waste oil adsorbent of the present invention can overcome above various deficiency.This adsorbent can be dispersed into a lot of small drops in the process stirring, and has increased the contact area of solution, has improved mass transfer effect; Minute criticality that waste oil and the aqueous solution are good, makes after its absorption separatedly easily with water, saves framework material.After absorption is saturated, can in acid solution, obtain desorption and regeneration, recycling, has reduced cost.In addition, this adsorbent is non-volatile, and nontoxicity does not affect operating personnel's health.Waste oil as harm food security, for the preparation of adsorbent, has cost advantage, can reach again the effect of waste recycling, has certain social benefit.
Summary of the invention
The present invention is primary raw material with product oil after waste oil crude oil or waste oil fine finishining, according to pending solion kind, adds corresponding modifier, under certain temperature and pressure, is processed into metal ion adsorbent.Then by profit, disperse contact to realize adsorption process.The adsorbent of supported ionic, then regenerate with stripping liquid, realize recycling of adsorbent, the metal ion being simultaneously desorbed is concentrated, and further recycles.
Technique of the present invention is followed successively by following steps:
(1) according to pending solion kind, in product oil after waste oil crude oil or waste oil fine finishining, add with sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, sodium chloride, sodium bromide, methyl alcohol, ethanol, propyl alcohol, n-butanol, DMF, organic amine, organic salt, sodium thiosulfate, ammoniacal liquor, sodium hydrogen phosphate, sodium dihydrogen phosphate, sodium phosphate, aphthenic acids, aliphatic acid, acetone, the modifier of one or more preparations in sodium sulfite, and at 50 ~ 200kPa pressure, under 40 ~ 150 ℃ of temperature conditions, add thermal agitation 0.1 ~ 5 hour, ultrasonic processing 0.1 ~ 5 hour, make waste oil metal ion adsorbent.
(2) pH of metal ion is adjusted between 2 ~ 9, temperature remains on 10 ~ 80 ℃, by stirring or alternate manner, makes profit two-phase mix mass transfer, continues 0.1 ~ 1 hour, then stratification.Water is lean solution after processing, and oil phase is rich in metal ion.
(3) divide oil-yielding stratum, be placed in the stripping liquid of one or more preparations of 5% ~ 60% sulfuric acid, hydrochloric acid, nitric acid and phosphoric acid, temperature remains on 10 ~ 80 ℃, profit is in a ratio of 1 to 5 to 5 to 1, by stirring or alternate manner, make profit two-phase mix mass transfer, continue 0.1 ~ 1 hour, then stratification.Water is denseer metal ion solution after desorb, by electrodeposition or alternate manner, further reclaims.Oil phase returns to (2) step and recycles.
Feature of the present invention is, this adsorbent can be dispersed into a lot of small drops in the process stirring, and increased the contact area of solution, improved mass transfer effect; Minute criticality that waste oil and the aqueous solution are good, makes after its absorption separatedly easily with water, saves framework material.After absorption is saturated, can in acid solution, obtain desorption and regeneration, recycling, has reduced cost.In addition, this adsorbent is non-volatile, and nontoxicity does not affect operating personnel's health.Waste oil as harm food security, for the preparation of adsorbent, has cost advantage, can reach again the effect of waste recycling, has certain social benefit.
