ISOTERM ADSORPSI KROMIUM(III) OLEH BIOMASSA Sargassum sp. (Isoterm Adsorption of Cromium(III) by Non-Living Sargassum sp.)

Biopropal Industri, 2020
Chromium (Cr) is one of the heavy metals with high toxicities and can be dangerous if it is thrown up directly into waters. One of the techniques to reduce heavy metal content with inexpensive, simple, effective and efficient is through adsorption process utilizing brown seaweed (algae) Sargassum sp. as adsorbent.

MODEL ADSORPSI ISOTERM ARANG AKTIF KULIT KOPI PADA PENURUNAN WARNA AIR LIMBAH PENGOLAHAN KOPI [PDF]

Agrin, 2021
Pengolahan kopi menghasilkan air limbah kopi dan limbah padat beruapa kulit kopi. Air limbah pengolahan kopi mengandung flavonoid yang berpengaruh terhadap warna coklat gelap pada air limbah pengolahan kopi. Apabila air limbah pengolahan kopi dibuang langsung ke badan air tanpa adanya pengolahan, akan mengganggu kehidupan air.

Studi Model Isoterm Adsorpsi Kristal Violet oleh Biosorben Kulit Ubi Kayu (Manihot esculenta)

Jurnal Teknik Kimia USU, 2021
Crystal violet is a dye that has many uses, but its waste can be harmful to humans and the environment. Adsorption is the most useful method for removing crystal violet waste compared to other separation methods because of its efficiency and viability. Cassava peel is a material that has potential to be an adsorbent.
