Remazol black B removal capacity of economic organic wastes

Abstract

One of the most vital natural resources for the survival of life is water. Water is used in a variety of industries, including human consumption, economic growth, ecological maintenance, and energy production. Water contamination is becoming more and more of an issue as a result of population growth and industrial development. One of the most important pollutants causing water pollution is textile dyes. Remazol Black B (RBB) dye is a synthetic textile dye used in industry. One of the methods used for dye removal from wastewater is biosorption. Biosorption is an environmentally friendly, economical, and effective method with its low cost and capacity to bind pollutants such as dye. This study investigated the biosorption of RBB with orange peel, an organic waste. In addition to using orange peel powder simply, it was also used in a complex form with surfactant. The surfactant named Hexadecyltrimethyl ammonium bromide (HTAB) was used to see the change in biosorption capacity. pH, dye concentration, temperature, time and adsorbent dosage parameters were investigated. The best removal results were obtained using the following conditions: pH 2, 12.5 ppm dye concentration, 50°C temperature, 1440th minute, and 1g/L adsorbent quantity. According to the test results for both orange peel and orange peel with surfactant under the same conditions, the highest yields were respectively; 91.92% and 83.84%. Consequently, it has been determined that orange peel, which is organic waste, can be used for the removal of dyes from wastewater with high efficiency.
