摘要：

We attempt to develop the process for making agricultural cultivation solution from seawater using natural zeolitc. Mordenitc-type zeolite obtained from lizaka mine in Japan indicated highest reduction of Na+. Radish sprouts did not grow using seawater, the solution treated with natural zeolitc, the solution treated with AgNO3 after zeolite treatment, and the solution treated with natural zeolite after AgNO3 treatment, due to the high contents of Cl' and NO3 remained in these solutions. By combination of anion reduction treatment using calcined hydrotalcite and zeolite treatment, radish sprouts can be grown in the prepared solution.
