5. the biomass charcoal is added into 2000ml of 6wt% ferric phosphate solution to be soaked for 1 hour, then the biomass charcoal is washed by deionized water, and the biomass charcoal is dried at the constant temperature of 120 ℃ in a constant temperature box to obtain the ferric phosphate modified biomass charcoal.
6. Loading the ferric phosphate modified biomass charcoal into an adsorption column.
The method for alkaloid content comprises the following steps:
for the defatted camel milk in the first step, an alkaloid extraction method commonly used in the art, such as an aqueous solution extraction method, an organic solvent extraction method, a percolation extraction method, a supercritical fluid extraction method, and the like, may be used, and since the present application is a defatted camel milk, an alcohol solvent extraction method is used, wherein a 75% ethanol solution is used as an extractant. Table 1 shows the alkaloid content of the camel milk after degreasing of examples 1-3 and comparative examples 1-3.
TABLE 1
| Alkaloid content (mg/kg) | |
| Example 1 | 0.39 |
| Example 2 | 0.31 |
| Example 3 | 0.26 |
| Comparative example 1 | 0.85 |
| Comparative example 2 | 0.67 |
| Comparative example 3 | 0.56 |
| Comparative example 4 | 0.53 |
Since comparative examples 1 to 4 used the same conditions as in example 3, it was confirmed by comparing comparative example 1 with examples 1 to 3 that the biomass content in the modified biochar-treated defatted camel milk was significantly reduced. By comparing the comparative example 1 with the comparative examples 2, 3 and 4, it can be determined that the modified or unmodified biomass charcoal has an effect of reducing alkaloids in the defatted camel milk, and the modified effect is more obvious; comparing comparative examples 1-4 with example 3, it was determined that the effect of reducing alkaloids in skim camel milk by aluminum sulfate and ferric phosphate modified biomass charcoal was most pronounced.
The protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
