Abstract
The invention relates to a method for separating a copper ion, and belongs to the field of environment sample detection methods. The method for separating the copper ion comprises the following steps: adding 5mL of a separation water sample, 1.5mL of an ammonium thiocyanate solution and 1.5mL of a myristyl chloride dimethyl benzyl ammonium solution into a colorimetric tube of 25ml with a ground stopper, diluting with a buffer solution to 10mL, then adding 1.0g of sodium chloride solids, vibrating fully, and placing for a while; filtering precipitate suspending on the water phase, and dissolving precipitate with 5mL of ethyl alcohol, thereby obtaining the separated ethyl alcohol copper solution. The method for separating the copper ion has the most prominent advantages that a toxic organic extracting solvent is not required, and the separation effect is satisfactory; because the copper ion is one of the most important elements in determination in environment analysis, and the determination of the copper ion is frequently interfered by co-existing ions of ferrum, cobalt, nickel, manganese and aluminum ions, the establishment of a new method which is nontoxic, is simple, convenient and economical and can separate the copper ion rapidly has important significance.
Description
Technical field
The present invention relates to a kind of separation method of copper ion, belong to environmental analysis method field.
Background technology
In vital metabolic, copper is a kind of important trace element.But in soil or water, copper too high levels is then unfavorable to the growth of plant or fish, and fish even can be caused poisoning.Therefore, the monitoring of copper ion is one of important content of environmental analysis.Because in soil or water, the content of copper ion is lower, and often exist as iron, cobalt, nickel, manganese, aluminium, magnesium plasma mix with other metallic ion, during as detected copper ion, owing to cannot be separated completely copper ion, the normal interference by these metallic ions, affects the detection accuracy to copper ion.
For this reason, study that a kind of technique is simple, safety, operation are simple and easy, separation method fast to copper ion, there is certain necessity.
Summary of the invention
The present invention aims to provide that a kind of technique is simple, safety, operation are simple and easy, separation method fast to copper ion.
The separation method of copper ion of the present invention, comprises the following steps:
Be with in 25mL in the color comparison tube of grinding port plug and add 5mL separation water sample, 1.5mL ammonium thiocyanate solution and 1.5mL tetradecyl chloride base dimethyl benzyl ammonium salt solution, add 1.0g solid sodium chloride again after being diluted to 10mL with buffer solution, fully vibrate, place a moment.Filter the precipitation be suspended on aqueous phase, namely obtain the ethanol copper solution of separator well with 5mL ethanol dissolution precipitation thing.
Preferably, the concentration of ammonium thiocyanate solution of the present invention is 0.2mol/L; The concentration of tetradecyl chloride base dimethyl benzyl ammonium salt solution is 0.01mol/L, and buffer solution is the pH value prepared by Acetic acid-sodium acetate is the buffer solution of 4-6.
Separation method of the present invention, utilizes aqueous two-phase liquid-liquid extraction system separating metal ions.Its principle is, copper ion and ammonium thiocyanate, tetradecyl chloride base dimethyl benzyl ammonium form water-fast Ternary Complex in aqueous, under a small amount of sodium chloride exists, this Ternary Complex precipitation floats on aqueous top layer and becomes interface two-phase clearly with moisture, by quantitative flotation in phase process.And ferric ion, nickel ion, manganese ion, aluminium ion, magnesium ion plasma can not by flotation in this system, being separated of copper ion and these ions can be realized whereby.
Copper ion separation method of the present invention, the most significant advantage does not need to use poisonous organic extraction solvent, and separating effect is satisfactory, because copper ion is one of important element measured in environmental analysis, and it measures but Chang Shoutie, cobalt, nickel, manganese, aluminium ion coexisting ion interference, thus set up a kind of nontoxic and easy, economy, quick separating copper ion new method has important practical significance.
Embodiment
Embodiment one:
(1) reagent prepares: the concentration of ammonium thiocyanate solution is 0.2mol/L; The concentration of tetradecyl chloride base dimethyl benzyl ammonium salt solution is 0.01mol/L; Buffer solution is the pH value prepared by Acetic acid-sodium acetate is the buffer solution of 4-6.
(2) detachment process: be with in 25mL in the color comparison tube of grinding port plug and add 5mL separation water sample, 1.5mL ammonium thiocyanate solution and 1.5mL tetradecyl chloride base dimethyl benzyl ammonium salt solution, 1.0g solid sodium chloride is added again after being diluted to 10mL with buffer solution, abundant vibration, places a moment.Filter the precipitation be suspended on aqueous phase, namely obtain the ethanol copper solution of separator well with 5mL ethanol dissolution precipitation thing.
Embodiment two: the separating effect of copper ion in mixed solution
By copper ion separation method of the present invention, be separated certain mixed ion solutions, its separating resulting as shown in Table-1.
Table-l separating resulting
Separating resulting shows, body series can make copper ion be well separated with iron, cobalt, nickel, manganese, aluminium ion.In polyion mixed system, this several ion is not also substantially by flotation, and the flotation behavior of each ion is identical with situation during its individualism.Therefore, sharp separation method of the present invention is a job highly significant to separating copper ion from mixed liquor.
