specific Embodiment approach 1

[0013] Specific embodiment one: a kind of method of reducing nickel content in heavy carbonated mineral water of Wudalianchi in this embodiment is to be finished according to the following steps:

[0014] 1. Immerse the activated carbon in the nitric acid solution to obtain the modified activated carbon;

[0015] 2. Add the modified active carbon into Wudalianchi heavy carbonated mineral water for adsorption to obtain Wudalianchi heavy carbonated mineral water with nickel removed.

specific Embodiment approach 2

[0016] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the concentration of the nitric acid solution in step 1 is 0.5 mol / L˜1.5 mol / L. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0017] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the concentration of the nitric acid solution described in step 1 is 1 mol / L. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for reducing the nickel content in bicarbonate mineral water of Wudalianchi, and relates to a method for removing nickel in water. The invention aims to solve the problem that the existing water treatment technology is mostly applied to sewage and is not suitable for reducing nickel in mineral water. The method comprises the following steps: immersing activated carbon into a nitric acid solution to obtain modified activated carbon; and adding the modified activated carbon into the bicarbonate mineral water of the Wudalianchi for adsorption to obtain the nickel-removed bicarbonate mineral water of the Wudalianchi. When the method is used for removing the nickel in the bicarbonate mineral water of the Wudalianchi, the removal rate of the nickel can reach 13.81%. The method is suitable for removing nickel in the bicarbonate mineral water of the Wudalianchi.

Description

technical field [0001] The invention relates to a method for removing nickel in water. Background technique [0002] Mineral water has become a common drink in daily life. It is everywhere in supermarkets, shopping malls, canteens, and convenience stores. The groundwater movement in the Wudalianchi volcanic rocks has formed many natural cold mineral springs with rich chemical components, rich in carbon dioxide, and has a very high medical and health care effect. Wudalianchi mineral water belongs to the strontium siliceous bicarbonate-carbonic acid type drinking natural mineral water, in which the four indicators of strontium, metasilicate, free carbon dioxide and total dissolved solids all meet the requirements of GB8537 limit indicators (only one of the limit indicators Just meet it), it is a compound drinking natural mineral water. Most of the domestic mineral water source water is non-aerated, and Wudalianchi mineral water naturally contains carbon dioxide, which is a r...
