Air adalah salah satu komponen utama dalam kelangsungan makhluk hidup terutama bagi manusia. Air yang dibutuhkan adalah air bersih yang dapat digunakan dalam kegiatan sehari-hari. Namun seiring berjalannya waktu, peningkatan populasi dan pencemaran lingkungan yang disebabkan oleh kegiatan manusia dan limbah pabrik mengakibatkan pencemaran air bersih. Air yang tercemar dapat mengandung zat kimia berbahaya seperti logam berat sehingga berdampak pada kesehatan. Oleh karena itu, pengolahan air bersih perlu dilakukan sebagai upaya untuk mempertahankan pasokan air bersih yang dapat dilakukan dengan proses filtrasi (penyaringan). Penelitian ini dilakukan dengan tujuan untuk mengetahui daya serap logam besi dan kadmium oleh adsorben nano filter yang dianalisis secara spektrometri serapan atom serta pengaruh penggunaan variasi jenis adsorben nano filter dalam penelitian terhadap kadar logam. Hasil penelitian diperoleh daya serap filter terhadap logam besi dengan kombinasi sedimen dan karbon aktif 0%, adsorben nano filter sedimen dan pasir silika sebesar 83,86%, sedimen dan manganes greensand sebesar 37,13% dan kombinasi keempat adsorben nano filter (sedimen, karbon aktif, pasir silika, manganes greensand) sebesar 61,13%. Sedangkan daya serap filter terhadap logam kadmium pada kombinasi adsorben nano filter sedimen dan karbon aktif sebesar 28,62%, sedimen dan pasir silika sebesar 97,21%, sedimen dan manganes greensand 10,36% dan keempat adsorben nano filter (sedimen, karbon aktif, pasir silika, manganese greensand) sebesar 66,51%. Data yang diperoleh menunjukkan bahwa kombinasi adsorben nano filter sedimen dan pasir silika layak digunakan karena memiliki daya serap paling baik terhadap kadar logam besi dan kadmium.

Water is an important component in the survival of living things, especially humans. The water needed is clean water that can be used in daily activities. However, population growth and environmental damage caused by human activities and industrial waste have resulted in clean water pollution over time. Polluted water can contain harmful chemicals, such as heavy metals, which can have an impact on health. Therefore, clean water treatment needs to be done in an effort to maintain a supply of clean water, which can be done with a filtration process. This study aims to determine the absorption capacity of ferrous and cadmium metals using adsorbents analyzed by atomic absorption spectrometry and using of various types of nano filter adsorbents in research on metal content. The results showed that the filter had an absorption capacity of 61.13% for iron metal with a combination of sediment and activated carbon at 0%, sediment and silica sand at 83.86%, sediment and manganese greensand at 37.13%, and a combination of the four adsorbents (sediment, carbon active, silica sand, manganese greensand) at 61.13%. While the absorption capacity of the filter for cadmium metal in the combination of sediment and activated carbon was 28.62%, that of sediment and silica sand was 97.21%, that of sediment and manganese greensand was 10.36%, and that of the four adsorbents (sediments, activated carbon, silica sand, and manganese greensand) was 66.51%. The data obtained showed that the combination of sediment and silica sand was feasible to use because it had the best absorption of iron and cadmium levels.
