以活性炭为脱色剂、碳酸钠为脱氟剂，对净化湿法磷酸工艺中的影响因素进行研究，确定了湿法磷酸脱色脱氟同步进行的最佳工艺条件：采用1.0%湿法磷酸用量的活性炭，并添加1.1倍理论脱氟用量的Na2 CO3，在50℃下反应120 min，处理后的湿法磷酸透光率达到80%以上，脱氟率也高于70%。
이활성탄위탈색제、탄산납위탈불제，대정화습법린산공예중적영향인소진행연구，학정료습법린산탈색탈불동보진행적최가공예조건：채용1.0%습법린산용량적활성탄，병첨가1.1배이론탈불용량적Na2 CO3，재50℃하반응120 min，처리후적습법린산투광솔체도80%이상，탈불솔야고우70%。
The influencing factors of purified wet-process phosphoric acid with activated carbon and Na2 CO3 as decoloring agent and defluorinating agent were studied. The best technological conditions were as follows:dosage of activated carbon was 1. 0% of wet-process phosphoric acid,dosage of Na2 CO3 was 1. 1 times theoretical amount,reaction temperature was 50 ℃ and time was 120 min. Under these condi-tions,light transmittance reached above 80% and the defluorination rate reached above 70%.
