the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...

background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...

In summer at night in the Bering Sea hydromedusae and scyphomedusae formed dense aggregations at the surface in convergences apparently produced by Langmuir circulation cells. During strong winds distance between parallel rows regularly exceeded 100 m; densities of medusae within rows reached 1,000 m-3. Physical and behavioral factors can increase spatial aggregation and thereby alter the rate ...

Timbal merupakan salah satu logam berat pencemar air yang sangat berbahaya. Salah metode dapat digunakan untuk menghilangkan kandungan tersebut adalah adsorpsi. Dalam proses adsorpsi, pemilihan adsorben penting memaksimalkan Karenanya, mengetahui karakteristik dan performa dalam menyerap berat. Model isoterm memprediksi dari suatu adsorben. Penelitian ini dilakukan meninjau ampas teh ion timbal...
