High concentrations of chromium in the soil have a toxic effect on the living organisms in the soil ecosystem. If chromium, which is not an absolute essential element, accumulates in plants, it causes structural changes, causing a decrease in plant growth... see more

Citrate-capped gold nanoparticle (GNP) was used as a ligand for chromium chelating, and chromium ions reaction led to GNP aggregation. The color change of GNP by aggregation in the presence of chromium is a simple and rapid colorimetric test for these ion... see more

Elektroplating hard chromium merupakan salah satu jenis metode pelapisan yang sering digunakan untuk memberikan sifat tahan korosi dan tahan aus karena sifatnya yang keras, namun banyak jenis cacat yang terjadi pada hasilnya salah satu faktor penyebabnya ... see more

Hexavalant chromium is considered the most toxic form because of its high solubility in water. Cr is known to induce production of elevated concentration of reactive oxygen species (ROS) resulted in macromolecule damage. Plants are having unique mechanism... see more

The impact of supplementing chelated chromium (Cr) in transition cows has increased recently. The objective of this study was to conduct a systematic review of randomized controlled trials to evaluate the effectiveness of supplementation of chelated chrom... see more

ABSTRAK Karbon aktif telah digunakan sebagai adsorban dalam pengolahan limbah cair industri dan terbukti mampu menyerap ion logam berat seperti Hg, Cu, Fe, namun kurang efektif terhadap ion logam hexavalent chromium (Cr.VI). Salah satu upay... see more

In the production of chromium and in the process of transportation of chromiumcontaining materials, contamination of natural waters and soils with chromium compounds inevitably occurs. In this paper, the sorption of chromium (VI) ions with carbon sorbents... see more

Chromium doped Tin oxide nanoparticles with chromium concentrations ranging from 1 to 5 wt% were synthesized by microwave irradiation technique. Standard characterization techniques were used to understand the characteristics of the nanoparticles obtained... see more

Teak sawdust is a waste of the furniture industry. The main compound content is cellulose, which contains hydroxyl groups so that can be used as adsorbent. This work aims to determine adsorption capacity and isotherm adsorption pattern of teak sawdust act... see more
