Объектами исследования служили пробы песков, отобранные на побережье рек Хонг (вблизи столицы г. Ханой), Тхубон (провинция Куангнам), Тхачхан (провинция Куангчи) и на побережье моря (вблизи г. Хатинь). В этих местах находятся разнообразные промышленные и сельскохозяйственные предприятия, а также активно развивается туристический бизнес. Предметом исследования служили гранулометрические характеристики песка и его минералогический состав. Для изучения минералогического состава проб песков применялся метод рентгенографического фазового анализа, который на основании полученных рентгенограмм позволяет определить минералогический состав изучаемых проб. Установлено, что в их составе преобладает минерал α-кварц SiO2, а также содержится некоторое количество α-корунда Al2O3 и прочих примесей. Для исследования гранулометрических характеристик песков применялся стандартный метод ситового анализа. В работе были определены доли различных фракций проб песка, средний размер зерен и коэффициент однородности, насыпной вес и величина пористости, а также величина удельной поверхности песка.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the presented work is a thorough determination of the characteristics of the coastal sands in Vietnam for the subsequent study of their sorption capacity. The objects of the study are sand samples collected on the banks of the Hong River (near the capital Hanoi), ThuBon (Quang Nam Province), Thachhan (Quangchi Province) and on the sea coast near the city of Hatin. Various industrial and agricultural enterprises are located in these places, in addition, the travel industry is actively developing here. The subject of the study is the granulometric characteristics of sand and its mineralogical composition. To study the mineralogical composition of sand samples the method of X-ray phase analysis is used, which allows to determine the mineralogical composition of the studied samples on the basis of the X-ray images obtained. It has been found that the mineral α-quartz SiO2 prevails in their composition, and there is also a certain amount of α-corundum Al2O3 as well as other impurities. To study the granulometric characteristics of the sands, the standard method of sieve analysis is used. The proportions of various fractions of sand samples, the average grain size, uniformity coefficient, bulk weight, porosity, as well as the specific surface area have been determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>песок</kwd><kwd>рентгенография</kwd><kwd>гранулометрия</kwd><kwd>минералогический состав</kwd><kwd>пористость</kwd><kwd>объемный вес</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sand</kwd><kwd>radiography</kwd><kwd>granulometry</kwd><kwd>mineralogical composition</kwd><kwd>porosity</kwd><kwd>bulk weight</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chen Y.
