dc.description.abstractEnvironmental pollution has increased along with the world’s population; the pollution of water includes any water contaminated by chemical and bacterial particulate matter, decreasing the water quality. The adsorption process is considered to be one of the best treatments for water pollution because of the cost of operation, convenience and simple design compared with other techniques, and it has high removal efficiency. This research investigates the Langmuir and Freundlich adsorption properties and characteristics of 13 types of date pits selected from different countries: Sukkary and Khalas from Kuwait; Berhi from different countries of origin, such as Jordan and Saudi Arabia; Medjool from Palestine; and Ajwat Almdena, Helwa, Hamraa, Dahsya, Maskanya, Gasbaa, Fanhaa and Debsa from Saudi Arabia. Two chemicals were used in the research, methylene blue and phosphoric acid (H3PO4). The standard curve and activation processes for date pits were the chosen methods in the study. The conclusion is that different types of date pits have different properties. The highest dateto- date-pit ratio was for Debsa, at 15.2 %, and the lowest ratio was for Maskanya, at 4%. For the concentration of 100 g, the highest adsorption was for Berhe date pits from KSA, at 0.015 mg/l. For the concentrations of 50 and 25 g, the highest adsorption was for Berhe from Jordan, at 0.015 mg/l. For the concentration of 12.5 g, the highest adsorption was for Sukkary date pits, whereas for the concentration of 5 g, the highest rate of adsorption was for Gasba date pits. The highest removal efficiency was for Berhe from KSA, with an average value of 95.9%, and the lowest was for Ajwat Almadena, at 69.5%. All the date pits have Freundlich isotherms except for Dahsya, Khlas and Medjool, which have linear isotherms. The recommendations are that detailed characterization of the date pits should be considered, such as measuring the surface area and porosity, testing the adsorption properties with different wastewater types instead of methylene blue and determining the result of crushing date pits with different specific weightsen_US

dc.description.conclusionsDifferent dates pit types have different properties such as date pits to date weight ratio, color, taste, the original country, adsorption concentration and isotherm type. The highest date and date pits ratio was 15.2% for Debsa; the lowest ratio was 4% for Maskanya; and for 100 g concentration, the highest adsorption was 0.015 mg/l for Berhe date pits from KSA. For 50 and 25 g concentrations, the highest adsorption was 0.015 mg/l for Berhe from Jordan, and for a 12.5 g concentration, the highest adsorption value was for Sukkary date pits. For a 5 g concentration, the highest rate of adsorption was for Gasba date pits; the highest removal efficiency was an average of 95.9% for Berhe from KSA; and the lowest was 69.5% for Ajwat Almadena.
