溴酸钾制备

【方法一】
电解法将由溴素与氢氧化钾合成的溴化钾用蒸馏水溶解配成电解液，电解24h后出第一批粗品，以后每12h取一次粗品，粗品经水洗除去溴化钾后用蒸馏水溶解，加少量氢氧化钾调pH值为8，保温0.5 h后过滤，将澄清滤液在结晶器中冷至室温，经结晶、分离、干燥，制得溴酸钾产品。其
阳极Br^-+6OH^-→BrO3^-+3H2O+6e
阴极6H⁺+6e→3H2↑
KBr+3H2O→KBrO3+3H2↑
氯氧化法石灰乳和溴素反应后通入氯气进行氯氧化反应，至pH值达6～7反应终止。除渣后，蒸发滤液。加入氯化钡溶液反应生成溴酸钡沉淀，将过滤后的沉淀加水悬浮，保持一定的温度加入碳酸钾进行复分解反应，粗品溴酸钾用少量蒸馏水多次洗涤后过滤、蒸发、冷却结晶、分离、干燥、粉碎，制得食用溴酸钾产品。其
6Ca(OH)2+6Br2→Ca(BrO3)3+5CaBr2+6H2O
CaBr2+6Cl2+6Ca（OH）2→Ca(BrO3)2+CaCl2+6H2O
Ca(BrO3)2+BaCl2→Ba(BrO3)2↓+CaCl2
Ba(BrO3)2+K2CO3→2KBrO3+BaCO3↓
【方法二】

由溴酸镁与氯化钾复分解而得： Mg(BrO₃)₂+2KCl→2KBrO₃+MgCl₂
将溴滴人氢氧化钾液中，可同时产生溴化钾和溴酸钾，再分别结晶而得(于沸水中重结晶)。
【方法三】
溴-氢氧化钾法
以工业溴素和氢氧化钾为原料，将氢氧化钾溶于1.4倍质量的水中，在不断的搅拌下通入溴，不久就析出白色沉淀即溴酸钾，继续加溴素至液体呈粉红色为止；冷却后分离出生成的溴化钾，再用水重结晶一次得成品溴酸钾。
6KOH+3Br2→5KBr+KbrO3+3H2O
溴酸钡法
在溴酸钡溶液中加入硫酸钾，经过滤除去硫酸钡沉淀，滤液冷却、结晶、干燥即得产品。
Ba(BrO3)2+K2SO4→2KbrO3+BaSO4↓
