Abstract
A lead-removing soap is prepared from soap matrix (45-55 wt.%), water (48-50) and EDTA (1.2-1.7) through loading soap matrix and water in a reactor, stirring while heating to 70-80 deg.C, adding the aqueous solution of EDTA, and extruding for shaping. It has high effect up to 98% on removing lead and other heavy metals.
Description
The present invention relates to a kind of laundry soap, particularly relate to a kind of lead-removing soap.
Existing laundry soap generally is made up of soap base and water, because plumbous water insoluble, therefore common laundry soap is not good comprising the washing effect of lead to heavy metal.
The purpose of this invention is to provide a kind of lead-removing soap, to remedy the above-mentioned deficiency of existing laundry soap.
A kind of lead-removing soap has soap base and water, it is characterized in that containing EDTA, and the weight percentage of soap base, water and EDTA is respectively 45-55,48-50 and 1.2-1.7, and the weight percentage sum of these three components is 100.
A kind of method of making lead-removing soap comprises soap base and portion water is put into reactor, is heated to 70-80 ℃ while stirring, after stirring, use the forcing machine moulding, it is characterized in that being heated to after 70-80 ℃, add the EDTA that is dissolved in reserved water to reactor.
The deleading of lead-removing soap of the present invention and other heavy metal effective, clearance can reach 98%.
Below by embodiment the present invention is described.
Get 48.4kg soap base (16 carbon fatty acid sodium), 1.6kgEDTA and 50kg water, earlier wherein 47.5kg water and 48.4kg soap base are placed in the reactor, be heated to 75 ℃ while stirring, with the 2.5kg water of reserving with the 1.6kgEDTA dissolving after, also put into this reactor, stir, be lead-removing soap of the present invention with the forcing machine moulding.
Deleading of the present invention is soaped very high to removal rate of heavy metal such as lead, mercury, cadmium, chromium when washing.The effect of deleading can be checked with the sodium sulfide solution of 1% (concentration expressed in percentage by weight).If also have more lead not to be removed, black will occur.
