Description
Technical field
The present invention relates to a kind of trace element chromium forage additive and preparation and using method.
Background technology
According to the difference of resin physical arrangement, ion exchange resin can be divided into gel-type and the big class of macroporous ion-exchange resin two.Gel type resin is the ion exchange resin of the homogeneous polymeric gel structure of a class appearance transparent, produces micropore after water suction in resin-phase, and counter ion is diffusible to enter to carry out ion exchange in the micropore that produced by absorbing water.The basic characteristics of macroreticular ion exchange resin are dry inside whole resin, wet or shrink, swelling all there is the duct more, bigger than general gel-type in water, thus surface area is big, in ion exchange process, the easy diffusion mobility of ion, exchange velocity is very fast.
Ion exchange resin is applied to the medical separation of analytical chemistry and purification pure water preparation and for a long time in the recent period for fields such as environmental conservation blood purifications.
Summary of the invention
It is an object of the invention to provide a kind of trace element chromium forage additive and preparation and using method.
Trace element chromium forage additive is a kind of cation exchange resin containing active chromium using chromic salt to be prepared from through ionic adsorption, exchange reaction with cation exchange resin, by weight percentage, chromium content in cation exchange resin is 0.05～0.5%.
The preparation method of trace element chromium forage additive, comprises the following steps:
1) cation exchange resin is placed in resin volume 1～the 0.5 of 2 times～2mol/L hydrochloric acid solution soak 2～5 hours, drain after acid solution with water rinsing to neutral；
2) it is cation exchange resin weight 0.05～the chromic salts of 0.5% by chrome content, it is pre-configured to the aqueous solution of 0.1～1.0mol/L, be slowly added to step 1 with stirring) resin in, the pH value detecting and regulating reactant liquor is 4.0～5.5, room temperature reaction 4～7 hours；
3) detecting step 2) pH value of reactant liquor, regulate with alkaline solution, making reacting liquid pH value is 6.0～7.0；Wash 2～5 times, filter or centrifuge dehydration；
4) by step 3) filter cake of gained dries at less than 70 DEG C, pulverizes, and obtains trace element chromium forage additive.
The chromate used in invention can be Chlorizate chromium, chromic nitrate, chromium acetate or chromic sulfate.Alkaline solution be concentration be the aqueous solution of sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate or the potassium bicarbonate of 0.5～5moL/L.
The using method of trace element chromium forage additive: in terms of chromium by account for the 0.1 of feedstuff gross weight～the additive capacity of 1.0mg/kg admix in aquatic animal, cattle, sheep, animal and fowl fodder.
The invention have the advantage that
(1) utilizing cation exchange resin can play the feature of absorption, exchange interaction with cation, loaded to by chromium in cation exchange resin, implementation is easy, and production suitable for industrialized, cost is relatively low.
(2) it is the control slow-released carrier of a kind of function admirable due to ion exchange resin, the chromium loaded is had control slow releasing function, thus substantially increases chrome uptake utilization rate.
(3) trace element chromium forage additive of the present invention is prone to mix with feedstuff, forms dispersed system, easy to use.
(4) trace element chromium forage additive obtained by the present invention has enhancing animal immunizing power, promotes growth and improves efficiency of feed utilization, improves the effect such as carcass lean meat percentage, egg fowl laying rate, applied widely.
