Abstract
This data article investigates cadmium removal efficiency using garbage ash as a cheap and effective adsorbent. Influence of different parameters, such as initial cadmium (II) concentration (mg/L), contact time (min), adsorbent dose (gr/L), pH and temperature (°C) were investigated. The characterization data of the garbage ash was determined using SEM analysis. The experimental data indicated that the adsorption of cadmium on garbage ash follows pseudo second order model and Langmuir isotherm model with R2 = 0.99. Also, the maximum adsorption capacity of adsorbent was 100.25 mg/g. Thermodynamic data showed that cadmium adsorption on garbage ash was a spontaneous and endothermic process. Based on acquired data, garbage ash could be proposed as an efficient and low-cost adsorbent for the removal of cadmium from aqueous solution.

This data article investigates cadmium removal efficiency using garbage ash as a cheap and effective adsorbent
The uptake of cadmium (II) by the adsorbent was determined based on the subtraction of the initial and final concentration of adsorbate Atomic Absorption Spectrophotometer (Shimadzu, AA-7000) was used for determination of cadmium (II) concentration Raw, analyzed For the preparation of adsorbent, garbage was placed in a furnace at 550 °C for 4.5 h to produce ash Cadmium (II) adsorption from aqueous solution using garbage ash Gonabad, Khorasan Razavi province, Iran Data are included in this article
The application of adsorbent of garbage ash due to cost-effectiveness and good potential is a suitable option for the removal of Cd2 þ from aqueous solution
Summary
The sampling of garbage was performed according to physical and chemical sampling methodology proposed by the Iranian National Standard Organization. The waste samples were collected from the garbage separated for composting in Mashhad solid waste management organization located in Mashhad, Iran. In order to prepare the adsorbent, the samples were placed in oven to remove any moisture. For the preparation of ash, the sample was placed in a furnace at 550 °C for 4.5 h and was kept in desiccator after cooling
