A method of making a nanocomposite is provided. The method includes dispersing nanocellulose and nano-bentonite in water and mixing to form a mixture. The method includes drying by heating the mixture at a temperature of at least 40° C. to form a dry mixture. The method further includes mixing the dry mixture with an alkylamine to form a nanocomposite composition. The method includes heating the nanocomposite composition at a temperature of at least 100° C. to form a paste. The method includes drying and milling the paste to form the nanocomposite. The nanocellulose is prepared from date-palm tree leaflets. The nano-bentonite is prepared from Saudi Arabia bentonite clay from the Khulays Mine. A method of treating water with the nanocomposite prepared by the method of the present disclosure is also provided.
