The invention relates to the field of adsorbent preparation, in particular to a preparation method of an adsorbent for cationic dye in water, which comprises the following steps: detecting a removal effect reference value, and determining an analysis mode according to the removal effect reference value; in the first analysis mode, whether the preparation volume is adjusted or not is determined according to a wastewater temperature reference value of a wastewater collection end, or a preparation adjustment mode is determined according to a dye concentration stable value; when the stable value of the dye concentration is in different threshold ranges, the pickling duration or the heating mode is correspondingly adjusted; in the adjustment of the heating mode, the heating speed is determined to be adjusted according to the concentration stability difference value, or the constant heating temperature is reduced and adjusted; in the second analysis mode, the preparation volume is determined to be adjusted accordin
