Gold recovery from secondary resources involves tremendous environmental and economic implications. In this work, four nucleobase (guanine, xanthine, hypoxanthine and adenine) modified cellulose microspheres were synthesized via radiation method for Au(III) capture from actual gold slag solution. The adsorption rapidly achieved equilibrium within 4 h. It was discovered that the pseudo-second-order and Langmuir model provided a superior match for the Au(III) adsorption process on adsorbents. At the optimal pH, the four adsorbents exhibited the outstanding adsorption capacities for Au(III) with ...
