Embodiment Construction

[0045] Further illustrate below in conjunction with the embodiment shown in accompanying drawing

[0046] The preparation method of the color-changing cloth that can quickly indicate heavy metal ions in water provided by the present invention is carried out according to the following steps:

[0047] 1) Material preparation:

[0048] (1) Chromogen working solution: Weigh 0.5-5g malachite green, dissolve it with 0.1%-1.0% ethanol aqueous solution and put it in a 100mL-1000mL volumetric flask to get the chromogen working solution (keep in a dark place away from light) );

[0049] (2) Dyeing material: dry cotton cloth;

[0050] 2) Cloth coloring:

[0051] (1) Pipette the developer working solution and water into a container, prepare a dye bath solution with a mass percent concentration of 0.1%-3.0%, and then drop in acetic acid to adjust the pH value to 2.5-7.0;

[0052] (2) After the dyeing bath is prepared, put it into the water bath, put the dry cotton cloth in the pot when th

Abstract

The invention relates to a functional textile and aims to provide a preparation method of a color-changeable cloth capable of quickly indicating heavy metal ions in water. The provided method should be simple and efficient to prepare the color-changeable cloth so as to realize rapid detection of the heavy metal ions in water. Another object of the present invention is to provide a method for detecting heavy metal ions in water by using the color-changeable cloth. The technical solution is as follows: the preparation method of the color-changeable cloth capable of quickly indicating heavy metalions in water is carried out according to the following steps: 1) material preparation: (1) color developing agent working liquid: weighing 0.5-5g of malachite green, and dissolving the malachite green with a 0.1-1.0% ethanol aqueous solution in a 100-1000mL volumetric flask to constant volume to obtain the color developing agent working liquid; and (2) dyeing material: a dry cotton cloth is adopted; and 2) cloth coloring.
