  • 方法二:合成法将氰化钠与硫黄反应生成硫氰酸钠，经除杂、活性炭脱色、过滤，滤液再经蒸发、过滤、结晶、分离，制得硫氰酸钠。其 NaCN+S→NaSCN 砷碱副产法以砷碱液脱除焦炉气中硫化氢时，生成硫氰化钠和氰钠，通过再生塔转化成硫代硫酸钠和氰酸钠。 上述砷碱液脱硫废液用硫酸处理，控制Ph值至4.5，使硫化砷析出，用纯碱中和，此时原料液中硫氰酸钠含量为130～160 g/L，硫代硫酸钠250～300 g/L，经真空蒸发，在15～16℃下结晶，分离除硫酸钠和硫代硫酸钠，粗品加水溶解，加人硫酸在90～100℃保温2h，使硫代硫酸钠转变为硫酸钠，过滤除去，滤液经加碱除铁，加氢氧化钡除残存的硫酸钠，上层净化后滤液再经真空蒸发、离心分离，即得纯度在98%以上、含氧化亚铁(FeO)量0.0005%以下的硫氰酸钠成品。其反应如下： 3Na2S2O3+H2SO4→3Na2SO4+4S+H2O Fe 3+ +3OH - →Fe(OH)3↓ Na2SO4+Ba(OH)
