استعمال الطحلب Nostoc linkia في خفض تراكيز الأصباغ المستخدمة في الصناعات النسيجية و المصرفة للبيئة المائية

الملخص EN

One genus of algae Nostoclinkiaas dried and livingwas used in reducingthe concentration of direct blue and reactive red dyes and color in textile factories.

The proper concentration 1 gm/L was prepared for each dye, however 0.005.

0.01, 0.03g/L were prepared from this concentration and used for 4 days of treatment.

The results confirmed that the efficiency of 1g from dried alga in reducing concentrations of dyes increased during period of treatment which recorded removal percent for direct blue at 0.005.

0.01, 0.03g/L concentrations as 83.11%, 73.05%, 63.6% after 4 days of treatment,while the removal percent for the same dye with 0.5 g of alga was57.44%,71.57% ،56.23% respectively.

Living filamentous alga was recorded higher removal percent for reactive red at 0.005, 0.01, 0.03g/L concentration after 96 hrfrom treatment 72.88%, 61.63%, 34.75% respectively.

The results illustrate increasing in algal biomass with increasing period of treatment and algal biomass in treatment, algal biomass of 1 g after 96 hr from treatment with direct blue dye were recorded 2.682,2.564,2.33g while algal biomass at 0.5 g after the same period of treatment 1.531, 1.395, 1.274grespectively.

Also, the living alga recorded increasing in biomass 47.73, 43.73, 34.97mg after 96hr from treatment with reactive red.
