| Abstract | ||||
| Adsorption studies using ultrasonic energy of acid red 150 of fluid liquor as for starting dyestuff concentration, temperature, dyeing time, pH, and sorbent amount had studied. Langmuir adsorption type was undertaken for depicting isotherms stability. The adsorbent suitability was examined by matching the adsorption information with Langmuir isotherm. The outcomes demonstrated that increasing of AR150 adsorption raised the concentration of both dyestuff and chitosan. A comparison between adsorption kinetics of four composites using AR150 with traditional and ultrasonic methods had been made. The time/dyestuff-uptake isotherms were declaring the improvement of dyestuff-uptake in adsorption second phase. Adsorption rate amounts, reaction half-time and standard affinity were studied and explained. The results explained that dyestuff uptake amounts for adsorbed composites using ultrasound technique are lower than those got in case of the conventional one. The isotherms showed lower dyestuff uptake of acid dyestuff red150 using ultrasonic technique relative to that in case of conventional one. | ||||
