Abstract
The silica-gel granular adsorbing-filtering material carrying positive charge is composed of aseptic granular silica-gel and aluminium hydroxide with weight ratio of 1:0.0023-0.0094. Said invented adsorbing-filtering material can adsorb virus particles in water, and its virus-adsorbing rate can be up to 98.6%, and its application is convenient.
Description
The invention belongs to enterovirus adsorptive concentration technology in the water.
At present in the adsorptive concentration drinking water viral aspect, adopt positive-charge charged filter material both at home and abroad, wherein use this method of aluminium hydroxide adsorptive concentration disease caused by infectious water poison the easiest, the colloid thing of this band positive electricity of aluminium hydroxide is directly added in the entry, reach the purpose of adsorptive concentration virus by flocculation sediment.But be to use the filtration water yield of this method adsorptive concentration fewer, generally can only filter the 1-5 premium on currency, the virus in can not the adsorptive concentration big yield, and the rate of recovery of disease caused by infectious water poison is lower, and the rate of recovery of virus has only 25-55%.Also need be equipped with main equipments such as centrifuge with aluminium hydroxide adsorptive concentration disease caused by infectious water poison, use very inconvenient.
The invention reside in the deficiency that overcomes prior art, positive-charge charged silica-gel-granular absorption filtering material virus, that the viral rate of recovery is high in a kind of energy adsorptive concentration big yield easy to use is provided.
The present invention is achieved in that a kind of positive-charge charged silica-gel-granular absorption filtering material is made up of aseptic particle silica gel and aluminium hydroxide, and the weight ratio of silica gel and aluminium hydroxide is 1: 0.0023-0.0094.The granular size of silica gel is the 60-100 order.Aseptic particle silica gel is evenly mixed with aluminium hydroxide, 45-80 ℃ dry.
The present invention has the following advantages:
1. the filtration water yield of adsorptive concentration virus of the present invention is bigger, detects the water yield and can reach 70 liters.
2. disease caused by infectious water poison adsorption rate height of the present invention, viral adsorption rate can reach 98.8%.
3. easy to use, do not need complicated centrifugation apparatus.
4. production technology is simple.
