“…Many biosorbents have been used to remove dyes from aqueous solutions, such as, Chlorella vulgaris (Aksu and Tezer, 2005), Azolla rongpong (Padmesh et al, 2006), Aspergillus foetidus (Patel and Suresh, 2008), Aspergillus parasiticus (Akar et al, 2009), Ulothrix sp. (Dogar et al, 2010) and Nostoc linckia (Mona et al, 2011), but studies about the use of S. platensis are very limited.…”

-The equilibrium and thermodynamics of azo dye (tartrazine and allura red) biosorption onto Spirulina platensis biomass were investigated. The equilibrium curves were obtained at 298, 308, 318 and 328 K, and four isotherm models were fitted the experimental data. Biosorption thermodynamic parameters (ΔG, ΔH and ΔS) were estimated. The results showed that the biosorption was favored by a temperature decrease. For both dyes, the Sips model was the best to represent the equilibrium experimental data (R 2 >0.99 and ARE<5.0%) and the maximum biosorption capacities were 363.2 and 468.7 mg g -1 for tartrazine and allura red, respectively, obtained at 298 K. The negative values of ΔG and ΔH showed that the biosorption of both dyes was spontaneous, favorable and exothermic. The positive values of ΔS suggested that the system disorder increases during the biosorption process.

In recent years, reactive dyes have been widely used in textile industries with particular efficiency. They dyes are often toxic, carcinogenic and mutagenic. Improper treatment and non-scientific disposal of dyed wastewater from these industries into water sources has created many environmental problems and concerns around the world. The purpose of the present study is to investigate the efficiency of iron filings in adsorption of Reactive Red 198 from aqueous solutions. This study was conducted using an experimental method at the laboratory scale. In this study, the effects of operating parameters such as pH (1-11), initial dye concentration (40-400 mg/L), contact time (5-120 min) and iron dose (0.1-1 g) with a mesh of<100 were studied. Dye concentration was determined using a spectrophotometer at a wavelength of 520 nm. The results indicated that maximum adsorption capacity of the dye in question was obtained at pH 3, contact time of 60 min and adsorbent dose of 1 g. At initial dye concentration of 100 and 200 mg/L, by increasing the dose of waste iron from 0.1 to 1 g, the removal percentage increased from approximately 76.89% to 97.28% and from 22.64% to 68.03%, respectively. At pH 3, contact time of 5 min and constant waste iron dose of 0.8 g, the dye removal efficiency was 85.34%. By increasing the contact time to 120 min, the removal efficiency increased to 99.2%. Welding iron waste as an inexpensive and available adsorbent has an optimum ability for adsorption of Reactive Red 198 from aqueous solutions.

“…Additionally, Sivakumar et al (2014) reported the activity of Aspergillus in remediation of textile wastes for safe environment. Similarly, the most toxic Azo dyes from textile wastes were acted upon by A. flavus biomass (Akar et al, 2009;Ali et al, 2009;Singh and Singh, 2010). Various applications of A. flavus have been reported including pretreatment of industrial wastes before they are released to the environment (Esmaeili and Kalantari, 2012).…”

Manufacturing industries contribute about 8% of the gross domestic products (GDP) whereas leather and textile industries supply 18% employments of manufacturing industries in Tanzania. Manufacturing industries merely depend on agriculture for raw materials and other inputs. However, processing of leather and textiles requires a lot of inputs, many of them supplied from agricultural produce and some are imported from developed nations. In vast developing countries, including Tanzania, manufacturing industries are constrained by limited production technology and the allied costs than raw materials. The conventional processing of leather and textiles requires immense technological investment that is associated with high production cost. In Tanzania, inputs such as soaking, bating and tanning agents for tannery industries are expensive and sometimes not readily available due to importation costs. On the other hand, management of waste effluents from leather and textile processing is the major impediment for development of these industries. However, natural processing of covering materials by using fungal biotechnology is of great concern in Tanzania to avert the prevailing constrains. The application of fungal based biotechnology would reduce production cost and health consequences resulting from chemicals, particularly, chromium. The effects of toxic chemicals from leather and textile industries would be mitigated by employing non-viable Aspergillus biomass in the industrial processes.
