【摘要】 为了探明鄂尔多斯碱湖钝顶螺旋藻粉中砷的来源。以鄂尔多斯碱湖钝顶螺旋藻各种养殖原料、扩藻初期和养殖正常大棚的藻液和藻粉为材料对其砷含量进行了追踪研究。结果表明:藻液的砷含量主要由养殖用水、碳酸氢钠来供给,无论扩藻初期、正常生产时期还是长时间的养殖期内的藻液和藻粉中的砷含量都保持相对稳定,并且用蒸馏水辅助清洗可以减小藻粉砷含量。更多还原

【Abstract】 In order to detect sources of arsenic in the Spirulina platensis power from the ordos alkali lake in Inner Mongolia,Arsenic content of culturing materials,nutrient solution and algal power in the period of initial cultivation and normal cultivation for Spirulina platensis was studied.The results showed that the water for culturing Spirulina platensis and NaHCO 3 providing the arsenic into the nutrient solution in the period of no culturing for Spirulina platensis,the arsenic content correspondingly keeps in a stable state not only in the period of initial cultivation and normal cultivation and long terms of cultivation,the arsenic content would cut down by cleaning the algal power auxiliarily with distilled water.更多还原
