Modification of the Adsorption Properties of Nanomaterials Based on Zinc Oxide and Tin Dioxide after Additional Activation in Argon Plasma

The modification of the adsorption properties of nanomaterials based on ZnO and SnO2, synthesized by the sol-gel method, after additional activation of their surface by argon plasma has been studied. Correlation between the adsorption properties and photocatalytic activity has been established. The scanning electron microscopy has confirmed the degradation of structure of nanomaterials with high-power plasma source and/or prolonged activation, and as a consequence, reduction of their photocatalytic properties

Alternatif Penambahan Limbah Batu Kapur dan Abu Sekam Padi sebagai Bahan Stabilisasi Tanah di Kecamatan Bangorejo Kabupaten Banyuwangi

Ekspansif land having the nature of flower and dwindle, high level ground water level when the rains and will do chap when dry season. The building can experience barstly of wall and degradation of structure as in area Bangorejo Banyuwangi. So that require to be conducted by stabilization to land by adding density and inactive material, debasing surface, changing ugly land, and also add other material so that happened reaction of chemically or nature to the land. In this research is conducted by addition of materials mixture Waste Limestone and Dusty Chaff to the ekspansif land, so that can improve the nature of existing land. Sampel taken away from Bangorejo Sub-Province Banyuwangi which consist of 15 dried land example with each composition 3 example to 5 treatment phase. Result of data analysis show the existence of repair of land characteristic, that is water rate, specific gravity, liquid boundary, plastis boundary and plasticity index of land go down, so that yield low add-dwindle potency of land. At addition mixture of limestone waste 20 % and dusty chaff of paddy 5 % obtaining optimal result, that is yield strength become 0,281 kg/cm2 and energy support of land become 9,378 ton/m2.
