Biosorption Potential of Dry Biomass of Parthenium Hysterophorus, and Euphorbia Helioscopia from Heavy Metal Solution in a Column Method

The study was carried out to determine the biosorption capacity of three wild plants Euphorbia heliscopia (Sun spurge), and Parthenium Hysterophorus (Gajar buti) by using column method. The experiment was conducted in Environmental biotechnology lab of University of Okara, located in Renala Khurd, District Okara, Pakistan. The plants biomass was treated with tap water, 10 ppm, 20 ppm and 30 ppm chromium solution. The experiment was repeated three times within three weeks and average data was collected. The metal analysis was done by using AAS (Atomic Absorption Spectrophotometer). The results analysed that Parthenium Hysterophorus had greater capacity (25.060 mg g-1) to absorb chromium metal as compared to Euphorbia heliscopia (5.0300 mg g-1) at 30 ppm chromium concentration and with increasing the metal ion concentration the rate of biosorption increased. The results concluded that plant Parthenium Hysterophorus has the highest potential to accumulate chromium.
