“…Kedua beban pencemar itu bukan hanya berasal dari industri tapi juga dari aktivitas domestik (rumah tangga, perkantoran dan perdagangan) di sekitar DAS. Polutan organik dalam limbah berkurang secara proporsional dengan jumlah COD yang diserap oleh adsorben [24]. Hasil penelitian ini telah membuktikan bahwa mineral bentonit sebagai adsorben alam mampu mereduksi zat waran dan COD secara efektif.…”

Pembangunan berkelanjutan diberbagai aspek termasuk industri telah meningkatkan kesejahteraan masyarakat, namun juga mengakibatkan kerusakan lingkungan. Kegiatan industri menghasilkan banyak limbah yang mekanisme pengolahannya belum tepat sehingga mencemari perairan terutama sungai. Industri tekstil setiap harinya membuang ratusan ton limbah cair ke sungai. Limbah tersebut mengandung zat warna dan polutan organik (Chemical Oxygen Demand/COD) yang bersifat toksik sehingga menggangu ekosistem perairan dan kesehatan manusia. Teknologi remediasi dengan menggunkan adsorben alami menjadi salah satu pilihan yang tepat untuk pengolahan limbah tekstil. Zeolit dan bentonit merupakan mineral alam yang jumlahnya melimpah dan murah serta mempunyai kemampuan adsorpsi yang baik. Pada penelitian ini zeolit dan bentonit diuji kemampuannya untuk mereduksi warna dan COD dalam limbah cair industri tekstil dengan sistem bed reactor. Limbah dialirkan ke dalam reaktor dengan laju 10 ml/menit secara kontinyu selama 24 hari. Ada 4 jenis adsorben yang digunakan yaitu zeolit alam, zeolit aktif, bentonit alam dan bentonit aktif. Hasil uji kemampuan adsorben menunjukkan bahwa bentonit aktif paling efektif dibandingkan adsorben lainnya dalam menurunkan polutan yaitu sebesar 83,89% warna dan 95% COD. Jumlah zat warna yang terserap yaitu sebanyak 364,59 mg/g selama 17 hari dan COD sebanyak 1946,92 mg/g selama 19 hari. Berdasarkan hasil tersebut, aplikasi adsorben alam dinilai efektif dalam mereduksi warna dan COD sehingga mengurangi beban pencemar yang masuk ke sungai.

“…In addition to the inorganic–organic compatibility, the loading and size of TiO 2 also affect their dispersion. A surface modification of the nanofiller through functionalization using bridging agents or surface compatilizers such as silane [ 106 , 107 ], amine [ 108 ], and polydopamine [ 109 , 110 , 111 ] are often required to improve the dispersion. Some of the expected physical properties of nanocomposite membrane such as mechanical properties are highly dependent on the uniformity of nanofiller dispersion as the agglomerations of nanofillers reduce the load transfer efficiency between the nanofiller and organic phases [ 112 ].…”

Membrane technology has become increasingly popular and important for separation processes in industries, as well as for desalination and wastewater treatment. Over the last decade, the merger of nanotechnology and membrane technology in the development of nanocomposite membranes has emerged as a rapidly expanding research area. The key motivation driving the development of nanocomposite membranes is the pursuit of high-performance liquid separation membranes that can address the bottlenecks of conventionally used polymeric membranes. Nanostructured materials in the form of zero to three-dimensions exhibit unique dimension-dependent morphology and topology that have triggered considerable attention in various fields. While the surface hydrophilicity, antibacterial, and photocatalytic properties of TiO2 are particularly attractive for liquid separation membranes, the geometry-dependent properties of the nanocomposite membrane can be further fine-tuned by selecting the nanostructures with the right dimension. This review aims to provide an overview and comments on the state-of-the-art modifications of liquid separation membrane using TiO2 as a classical example of multidimensional nanomaterials. The performances of TiO2-incorporated nanocomposite membranes are discussed with attention placed on the special features rendered by their structures and dimensions. The innovations and breakthroughs made in the synthesis and modifications of structure-controlled TiO2 and its composites have enabled fascinating and advantageous properties for the development of high-performance nanocomposite membranes for liquid separation.

Polyamide 6 (PA6) fiber has the advantages of high strength and good wear resistance. However, it is still challenging to effectively load inorganic antibacterial agents into polymer substrates without antimicrobial activity. In this work, graphene oxide is used as a carrier, which is modified with an aminosilane coupling agent (AEAPTMS) to enhance the compatibility and antimicrobial properties of the inorganic material, as well as to improve its thermal stability in a high‐temperature melting environment. Cuprous oxide‐loaded aminated grapheme (Cu2O‐GO‐NH2) is constructed by in situ growth method, and further PA6/Cu2O‐GO‐NH2 fibers are prepared by in situ polymerization. The composite fiber has excellent washing resistance. After 50 times of washing, its bactericidal rates against Bacillus subtilis and Escherichia coli are 98.85% and 99.99%, respectively. In addition, the enhanced compatibility of Cu2O‐GO‐NH2 with the PA6 matrix improves the orientation and crystallinity of the composite fibers. Compared with PA6/Cu2O‐GO fibers, the fracture strength of PA6/Cu2O‐GO‐NH2 fibers increases from 3.0 to 4.2 cN/dtex when the addition of Cu2O‐GO‐NH2 is 0.2 wt%. Chemical modification and in situ concepts help to improve the compatibility of inorganic antimicrobial agents with organic polymers, which can be applied to the development of medical textiles.
