Direct Red 81, a dye widely used in textile industries, is frequently detected dye in water resources. High costs, the formation of hazardous byproducts, and high energy costs restrict the use of some removal methods. Therefore, the main objectives of this research are the feasibility of using soil containing iron as a low cost adsorbent to remove (Direct Red 81) from aqueo...

In this work, we investigated the effect of various adsorption parameters (solution pH, temperature, contact time, and presence phosphate nitrate ions) on Reactive Red 120 (RR120) dye by Polyamide Nylon 6 (PN6) microplastics (MPs). Maximum uptake was achieved at pH 2.0, temperature rise from 295 to 313 K resulted in decrease RR120 sorption PN6. Equilibrium after 7 h, kinetic data obeyed pseudo-...

background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...

conclusions while the crp value was in patients with acute brucellosis in the current study, the mpv, rdw and leukocyte counts were within the normal range. crp value remains the most valuable inflammatory marker in cases of acute brucellosis. results the follow-up within the year after treatment was examined. the values of age, gender, leukocyte count, c-reactive protein, rdw and mpv were reco...

in this work, removal of c. i. acid red 14 was investigated by pumice stone as a low cost adsorbent. various parameters such as initial dye solution, contact time and ph were studied. removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of ph. three isotherm models were studied. linear and non-linear regression analyses were used for de...

conclusions the uv/zno system has been found an effective process with 90.2% cod removal and 95.6% dye removal after 50 minutes treatment. materials and methods in this work, zno catalyst and mercury lamp (uv-c, 254 nm) have been applied for removal of the c.i. sulphur red 14 dye from aqueous environments. the influence of various parameters such as the amount of zno, initial dye concentration,...
