The invention discloses a preparation method of environmentally friendly gold-bearing catalyst. Said method includes the following steps: uniformly mixing carrier iron salt solution and gold salt solution, stirring them at 20-80deg.C, using sodium carbonate as precipitant to make precipitation, regulating final pH value to 7-10, continuously stirring for 1.5-4hr, standing still for 2.5-6hr, filtering and drying for 4-24hr at 20-80deg.C so as to obtain the invented catalyst. Said method has no need of washing or roasting. Said catalyst has the strong potency for resisting poisoning of CI-.
