As shown in table 1, if confirming increases the amount for the iron powder being added in seaweed, the arsenic the amount of dissolution of seaweed is reduced.
In addition, the test for having No.1~No.3 of iron powder is added in the seaweed of aqueous isloation state, add in pre-dry seaweed
The test for having entered No.5~No.7 of iron powder is compared, then confirming the former is greatly decreased the arsenic the amount of dissolution of seaweed.
In addition, in the test of No.3~No.8, the arsenic the amount of dissolution of dried object or mixture shows the discarded of Japan
The value of the standard max value 0.3mg/L or more of the arsenic the amount of dissolution of object facture defined can be true in the test of No.1 and No.2
Recognize the arsenic the amount of dissolution of dried object, the value shown is lower than the standard max value.
According to the above results, it may be said that when the iron powder more than a certain amount of being added in the seaweed of the state of moisture content, energy
Enough effectively inhibit the amount of dissolution of the arsenic from seaweed.In addition, according to heat run, it may be said that by heating seaweed, in seaweed
Contained arsenic is effectively dissolved out to moisture, therefore, when adding iron powder after the seaweed of the state of heating aqueous point, it can be expected that more
The inhibitory effect of high arsenic the amount of dissolution.
